******Question 2 and 3 requires you to look at week 4 document for instructions and requires week 4 assignment format . *************(documents attached)

Question 1:

Explain the function of the cardiovascular and respiratory systems as well as how these systems work together to meet the demands of activity. Discuss the process of gas exchange as well as coronary artery disease and chronic obstructive disease and explain how these chronic diseases can lead to dysfunction of these systems.

To complete the following activity, you will need paper, a pen, and a clock or stopwatch with a second hand. To begin, take the Physical Activity Readiness Questionnaire (Links to an external site.) (PAR-Q). The PAR-Q is a screening tool to determine if a person should check with his or her doctor prior to completing an exercise program. If it is determined that you should not exercise, please find an adult (18 years of age or older) family member or friend to complete the assessment for you who has been cleared to exercise through the PAR-Q assessment. You can record the results of your partner.

Measure resting heart rate (refer to page 13 of the text on how to take a pulse). Count your respirations in 1 minute. Record results.
If you are able to safely do so, exercise for 3 minutes (jog in place, do jumping jacks, jump rope, push-ups, sit ups, etc.)
Immediately take your pulse for 10 seconds. Record that number. Have your partner record your respirations for 1 minute.
Rest for 5 minutes. Take your pulse again for 10 seconds. Count your breaths again for 1 minute.

In your initial post:

Enter the results from the heart rate activity above.
Describe the function of the cardiovascular system and the respiratory system and how they work together.
Describe how the cardiovascular system adjusts to meet the demands of exercise. Use appropriate terminology such as stroke volume, respirations, and pulse.
Describe why an untrained person’s heart rate and breathing rate would take longer to return to a resting rate compared to a person who is in good physical condition.
Explain the relationship between heart rate and breathing rate during physical activity.
Discuss contributing factors to coronary artery disease (CAD). Explain how CAD leads to dysfunction of the cardiovascular system.
Discuss contributing factors of chronic obstructive pulmonary disease (COPD). Explain how COPD leads to dysfunction of the respiratory system.

Use two scholarly sources (one may be your course text) to support your initial post. All sources must be referenced and cited according to APA guidelines as outlined in the Ashford Writing Center. Your initial post should be at least 250 words in length.

RESULTS HEART RATE

Resting heart rate 80 for 1 minute; Respirations 25

Respirations for 1 min after workout –42

Pulse 5 mins after workout – 12

Respirations 5 mins after workout – 27

What is the function of the cardiovascular system and respiratory system and how do they work together?

Cardiovascular system is the body system that includes the heart, arteries, veins and capillaries and distributes blood throughout the body (Colbert, Ankeny & Lee, 2013). And the respiratory system removes carbon dioxide and gets oxygen to the body as needed. The two systems have to work together as the respiratory brings the air into the body system, then when the cells use the oxygen it creates carbon dioxide. Which is then carried in the blood stream to be released so it doesn’t cause damage. So, the cardiovascular system transports the oxygen and carbon dioxide to the correct organ through the blood.

Why is an untrained person’s heart rate and breathing rate would take longer to return to a resting rate compared to a person in shape?

The parasympathetic nervous system becomes more efficient and will slow your heart rate quicker as you become more physically fit (Wolfe, 2019). And the more you train your heart becomes in better shape.

Relationship between heart rate and breathing rate during physical activity.

During physical activity our hearts are working harder and to reduce the work of the heart we must increase the oxygen content of the blood that is going through the heart. To get more oxygen in the blood we breath harder. So during physical activity your heart rate and respirations increase.

CAD

High cholesterol can cause coronary artery disease, as it a plaque that builds in blood vessels and causes blockage. Which then limits the proper amount of blood flow to the cardiovascular system. Which then causes it to not work properly.

COPD

A major factor to COPD is the inhalation of cigarette smoke. These are individuals that smoke or that are around second-hand smoke. Breathing this bad smoke causes damage to your lungs and that is how you get COPD which is a disease when you have difficulty getting all the air out of your lungs.

Pulse (10 sec)- 6 Respiration (1 min)-19

The main functions of the cardiovascular system are; to transport nutrients, gases and waste products around the body, to protect the body from infection and blood loss, to help the body maintain a constant body temperature, and to help maintain fluid balance within the body (Busse, n. d.). The respiratory system is responsible for gathering oxygen from the outside environment and supplying it to the cells, and to remove the carbon dioxide produced by cellular metabolism, from the body. Additionally, it’s functions also include phonation, pulmonary defense and metabolism, handling bioactive materials, acid-base balance, and gas exchange (Levitzky, 2018). Together, both systems work to remove carbon dioxide and to make certain that organ tissues are receiving enough oxygen.

During exercise, the job of the cardiovascular system is to deliver blood and oxygen from the heart and lungs to the working muscles, so in order to meet oxygen and energy needs during exercise, both the heart rate and stroke volume increase, which in turn increases the cardiac output and respiration, in order to bring more oxygen to the lungs (St. Laurent, 2019).

According to Wolfe (n. d.), “The heart rate of a physically fit person returns to normal rhythm faster than that of an untrained person because of the training response on the body’s autonomic nervous system” (para. 1). This system regulates heart rate, blood pressure, breathing rate, and the release of glucose for energy. Additionally, as a person becomes more used to physical activity, the heart becomes more efficient in pumping out necessary oxygen.

As one begins to exercise, the sympathetic nervous system causes the heart rate to increase, the breathing pace to increase, and elevates blood pressure in order to circulate the oxygen needed during exercise (Wolfe, n. d.).

Coronary artery disease (CAD) happens when plaque builds up that causes the coronary arteries to become narrow, and decreases the bloodflow to the heart. Factors that contribute to CAD can include; family history, smoking, high blood pressure, diabetes, obesity, lack of physical activity, excess stress, and an unhealthy diet (Mayo Clinic, 2018). Inadequate blood supply to the heart can cause arrhythmia, plaque build up causes blood clots to form and a complete blockage can bring on a heart attack, and when this happens it can make a person more susceptible to heart failure (Mayo Clinic, 2018).

Chronic obstructive pulmonary disease (COPD) is a chronic inflammatory lung disease that causes obstructed airflow from the lungs, and can be caused by long term smoking, exposure to second-hand smoke, exposure to dust and chemicals from a job, age, and gender (Mayo Clinic, 2017). COPD can lead to chronic respiratory infections like colds, flu, and pneumonia, which can make it extremely difficult to breath and cause further lung tissue damage.

Week 4 Lab Exercise (Introduction)
Introduction
The circulatory system is the major transportation system for the human body. It
allows for transport of nutrients, gases, electrolytes, hormones and cellular waste.
Consider how important transportation of these substances is for maintenance of
the overall health of the human body. Disruptions to the proper functioning of the
circulatory system can result from various disease states and can have dire
consequences.
The blood vessels of the circulatory system make up a closed system for transport
of blood. As the heart contracts, blood is propelled from the left ventricle into the
aorta. From there, it travels through successively smaller arteries before reaching

arterioles, capillary beds, and nally tissues. Together with the heart, the circulatory
system is responsible for distributing blood to all the cells of the body.
Figure 1: The circulatory system showing the arteries in red and the veins in
blue.
There are two systems identi ed in the circulatory system: the pulmonary system
and the systemic system. The pulmonary system is responsible for transporting
blood to the lungs, where it becomes oxygenated. The systemic system is
responsible for delivering oxygenated and nutrient rich blood to the rest of the
body. Both are one-way systems, ensuring only oxygenated blood is pumped
through the body.

Arteries
Arteries are the largest vessels that transport oxygen-rich blood away from the
heart to the tissues of the body. However, there are two exceptions to this rule:
pulmonary arteries, which transport oxygen-poor blood from the heart to the
lungs; and, umbilical arteries which transport deoxygenated blood from the fetus
to the placenta. Arteries always consist of three layers, or tunica.

1. Tunica Intima: The inner layer facing the blood. It is composed of an innermost
layer of simple squamous epithelium surrounded by connective tissues.
2. Tunica Media: The middle layer. It is composed of smooth muscle with variable
amounts of elastic bers.
3. Tunica Adventitia: The outer layer. It is composed of connective tissue.
There are three types of arteries in the body. The largest arteries of the body, such
as the aorta, are called elastic arteries. Most of these vessels are nearby to the
heart, and have to expand as they receive blood from the heart. These arteries
have a large amount of elastic proteins in their tunica media, allowing them the
exibility to expand when a bolus of uid is ejected from the heart. When the heart
relaxes, the elastic properties of these arteries propel blood forward and the elastic
arteries return to their original size. Muscular arteries branch from elastic arteries
and distribute the blood across the body. Their name rises from an increased
percentage of smooth muscle in the tunica media, enabling the vessels to help
regulate blood ow. To slow blood movement, these vessels can constrict by
contraction of the smooth muscle, and to increase blood ow muscles relax and
they dilate. The nal subdivision from these arteries is a smaller vessel called the
arteriole. These sometimes microscopic vessels can also regulate blood ow
through vasoconstriction and vasodilatation.

Capillaries
The next branch in the circulatory system is the capillary. These vessels have extremely thin walls, consisting
only of the tunica intima, some only one cell layer thick. Capillaries penetrate most of the body’s tissue, creating a
highly branched network of capillary beds. The thinness of their walls allows oxygen and nutrients to di use from
the vessel into surrounding tissues, and carbon dioxide and other waste products to leave the tissues and enter
the capillary. Many of these vessels are large enough for blood cells to pass through in single line fashion,
maximizing the potential for exchange. The types of capillaries are outlined in Table 1.
Veins
After blood travels through the capillaries, it reaches a vein. Veins are the vessels that carry the oxygen-poor
blood to the heart, where it can be pumped back to the pulmonary system to be re-oxygenated. One exception to
this is the pulmonary vein, which carries oxygen-rich blood from the lungs to the left atrium of the heart. Postcapillary venules are the smallest vein. Similar to capillaries, veins are porous, but have smooth muscle scattered
throughout the tunica media. Di erent veins come together to form venules. These vessels possess the three
layers found in arteries (the tunica intima, tunica media, and tunica adventitia), but are still somewhat more
porous to allow the transfer of white blood cells out of the vessel. Although veins possess all three layers typical
to a blood vessel, the tunica intima and tunica media are much thinner in comparison to those found in the
arteries. However, the tunica adventitia is well-developed. In some veins, such as those found in the limbs, the
tunica adventitia creates aps inside the lumen of the vessel that form valves. Skeletal muscle surrounding veins
helps to pump the blood from chamber to chamber, with valves preventing back ow. This helps to regulate the
movement of the deoxygenated blood as it makes its way back to the heart.
Blood Pressure

Week 4 Lab Exercise (Introduction) | eScience Labs
Pressure is the driving force that keeps the blood owing throughout all of the branches of blood vessels.
Hydrostatic pressure on the walls of the blood vessels is generated when the heart pumps blood through an
artery. Systolic pressure of arteries, measured when the ventricles are contracted, is equal to about 120 mm Hg
in healthy adults. Diastolic pressure is measured when the ventricles are relaxed and is normally around 80 mm
Hg (millimeters mercury) in arteries. As blood travels throughout the arteries, resistance (and therefore pressure
and velocity of blood ow) is reduced due to the change in tunica layers.
Recall the increase in smooth muscle cells, and resulting regulation of blood ow in arterioles. As the blood
enters the arterioles (the main resistance vessels of the system), pressure is sharply reduced and continues to
decline in the capillaries. Blood pressure in veins is nearly zero. These measurements are useful diagnostic tools
to understand cardiovascular health, and are monitored closely by several systems in the body.
Figure 3: Blood volume in uences blood pressure.
Cardiac Output
Cardiac output, the amount of blood ejected from the left ventricle, and resistance in blood vessels are two
measures that the body can alter when blood pressure is too high or too low. The cardiovascular control center is
located in the medulla oblongata, and is involved in regulating blood volume and blood vessel resistance.
Higher brain centers and specialized sensors in blood vessels (baroreceptors for pressure and chemoreceptors
for chemicals) monitor the state of the circulatory system. Cardiac output can be increased by increasing the
heart rate as well as the force of contraction. Sympathetic cardiac innervation allows this control by the
cardiovascular center in the brain. Parasympathetic vagus innervation of the heart allows the nervous system to
decrease the heart rate. The vasomotor center is connected to sympathetic nerves that innervate smooth muscle
in arterioles. When the resistance in these vessels needs to be changed, nerves stimulate the smooth muscle of
arterioles accordingly.

The Reproductive System
Most systems in the body are required for survival. However, the reproductive system is unique as it is not
mandatory for individual survival. In simplest terms, the reproductive system functions to propagate a species.
Reproduction involves the production of sperm and eggs, the processes leading to fertilization, and embryonic
development. The primary sex organs are called gonads – testes in males and ovaries in females. These organs
secrete hormones and produce gametes. Male gametes are termed spermatozoa (sperm), and female gametes
are termed ova (eggs). Accessory reproductive organs include ducts, glands, and external genitals. The
reproductive role of the male is to produce sperm and deliver it to the female reproductive tract. The female
produces eggs, which, when fertilized with the sperm, creates the rst cell of a new individual. After fertilization
occurs, the female uterus provides a nurturing, safe environment for an embryo to develop into a fetus until
birth.
Male Reproductive Organs
The penis is a cylindrical organ that provides an exit route for urine and sperm. Internally, the penis consists of
three cylindrical masses of tissue, each of which is surrounded by a thin (but tough) layer of brous connective
tissue called the tunica albuginea. During erection, parasympathetic neurons stimulate dilation of the arteries
within the penis, causing the penis to enlarge and sti en. Similarly, ejaculation occurs when sympathetic
neurons stimulate the discharge of semen.
Two testis reside within the scrotum, a sac that hangs from the base of the penis. A vertical septum divides the
scrotum into left and right compartments, each of which encloses one testis. Optimal sperm production occurs at
https://esciencelabs.com/studentresource/week-4-lab-exercise-introduction

7/14/2019
Week 4 Lab Exercise (Introduction) | eScience Labs
a temperature of approximately 35 – 36 °C (which is 1 – 2 °C below the core body temperature). This is one reason
why the scrotum hangs outside the body.
The testes have both an endocrine function (testosterone production) and an exocrine function (sperm
production). The spermatic cord connects each testis to the body cavity. The coiled seminiferous tubules inside
each lobule unite to form a straight tube, called the tubulus rectus. Endocrine cells, called Leydig cells, cluster
along the seminiferous tubules, and secrete testosterone. Testosterone in uences spermatogenesis and some
of the secondary male sex characteristics. For example, within the genital tract, testosterone promotes the
development and control of the duct system and associated glands.
Each testes transports sperm through a system of long, twisted tubes that comprise the bulk of the organ. A twolayer outer membrane system called the tunica vaginalis surrounds each testis. The tunica albuginea, which lies
inside the tunica vaginalis, protrudes inward, divides each testis into lobules containing seminiferous tubules
where sperm production occurs. The epididymis is a comma-shaped organ that lies adjacent to each testis. Each
epididymis contains a tightly coiled tube called the ductus epididymis. Sperm are held in this organ to complete
their maturation here until ejaculation.
The remaining structures of the male reproductive system consist of the conduits and sources of secretions that
aid in the delivery of sperm to the body exterior or the female reproductive tract. Smooth muscle cells
surrounding the epididymis contract during ejaculation. This forces mature sperm into the next tube called the
ductus deferens (also called the vas deferens). The vas deferens is the tube through which sperm travel when
they leave the epididymis. Each tube loops around the bladder and joins the ejaculatory duct. The ejaculatory
ducts are short tubes that connect each vas deferens to the urethra. The urethra is the passageway for urine and
semen. The urethra ends at the external urethral ori ce.

Female Reproductive Organs
The ovary is the organ that produces eggs in the female reproductive system. Two ovaries are present in each
female and each is held in place by the mesovarium, the suspensory ligament, the broad ligament, and the
ovarian ligament. Each ovary is approximately the size of an almond. The ovary is covered by a layer of
epithelium and the tunica albuginea. The inside of the ovary is divided into two indistinct regions, the outer
cortex and the inner medulla. Ovarian follicles are embedded in the cortex. Each follicle contains a primary
oocyte surrounded by one or more layer of follicular cells that nourish the oocyte as it matures. The Fallopian
tubes (also called the oviducts or uterine tubes) transport the secondary oocytes away from the ovary and
toward the uterus during menstruation.
The uterus is a hollow organ in which fetal development occurs. It is characterized by four regions. The upper
region is called the fundus. The central region is called the body, the lower, narrow region is called the isthmus,
the cervix is a narrow region at the bottom of the uterus that leads to the vagina. The uterus is held in place by
the broad ligaments, uterosacral ligaments, round ligaments, and cardinal ligaments. The wall of the uterus
consists of the perimetrium, a serous membrane that lines the outside of the uterus, and the myometrium
containing several layers of smooth muscle. The endometrium is the highly vascularized mucosa that lines the
inside of the uterus.
Figure 6: Female reproductive organs.
The vagina serves both as the passageway for a newborn, and the site for sperm deposition. The upper vagina
surrounds the cervix, and the lower vagina opens to the outside at the vaginal ori ce. The vulvae make up the
external genitalia – the mons pubis, labia major, labia minora, the versibule, and the clitoris.
The mammary glands are a type of sweat glands that specialize in milk production. The milk-producing
secretory cells form walls of bulb-shaped chambers called alveoli that join together with ducts to form clusters
called lobules. Groups of lobules assemble to form a lobe. Each breast contains a single mammary gland

consisting of 15 – 20 lobes. Lactiferous ducts lead away from the lobes and widen into lactiferous sinuses that
serve as temporary reservoirs for milk. The ducts narrow again as they lead through a protruding nipple. The
nipple is surrounded by a ring of pigmented skin called the areola. During pregnancy, estrogen and progesterone
stimulate extensive development of the mammary glands and its associated ducts. After childbirth, various
hormones, namely prolactin, initiate lactation. When neurons are stimulated by the sucking of an infant, nerve
impulses activate the posterior pituitary to secrete oxytocin, stimulating contraction of the cells surrounding the
alveoli. Milk is then forced toward the nipple in what is called the letdown re ex.
