Respiratory System
1. The upper respiratory tract structures are found in the ________________ and
____________. The lower respiratory tract structures are mainly in the _____________
______________.
2. The three main parts of the upper respiratory tract are the __________, the __________,
and the _____________. The middle part is divided into three regions, the
____________, the _____________, and the ______________.
3. Major functions of the respiratory system include ______________ of air, and gas
___________. Respiratory organs also function in ______________, homeostasis of
_____, and the sensory function _____________.
4. Accessory structures of the respiratory system include the ___ _____ and ____________
which include the muscles used in ventilation, and the _________ cavity, which can be
used in place of the nose in breathing.
5. Air-filled spaces in bones around the nasal cavity are called the ______________
___________. They drain into the ____________ ___________.
6. The voice box, or ___________, is made up of cartilage and the vocal folds. The
______________ cartilage is larger and protrudes more in males. The __________
cartilage makes a complete ring. The _____________ covers the glottis, or opening of the
larynx, during swallowing.
7. The lower respiratory tract begins with the _________, which divides into the
_____________. At the ends of the branches, the structures of gas exchange, the
___________ are found.

8. Type II cells of the alveoli produce ___________ which helps keep the alveoli open by
decreasing ______________ _____________.
9. The organs containing the bronchi, bronchioles, and alveoli are the _______. The right
one has ___________ lobes, while the left has _______.
10. The sac around the lungs is the pleura. The ___________ layer covers the lung tissue.
The __________ layer lines the thoracic cavity. These layers produce a fluid that
_____________ the surfaces, minimizing friction.
11. Breathing, or ______________ of the lungs, has two phases: __________________,
moving air in, and _________________, moving air out.
12. Air moves because of pressure differences, moving from ________ pressure to
__________ pressure.
13. Pressure changes for ventilation are mostly caused by _____________ of the diaphragm
for inspiration, either at rest or forced inspiration. Expiration at rest does not involve
muscles, but is driven by ____________ ___________ of the rib cage and abdominal
organs, while forced expiration uses the ___________ muscles.
14. The volume of air in a normal breath is called the ___________ ____________, and is
about 500 mL. The volume of air that one can force out after a normal breath out is called
the ___________ _____________ ___________, and is usually about 1,000 mL or a little
more. The volume that one can breathe in after a normal breath in is called the
______________ _____________ _____________, and is larger than the other
respiratory volumes, averaging 3,300 mL. These three volumes added together make up
the ___________ capacity, which is the size of a maximum breath out after a maximum
breath in.

15. Air remaining in the lungs after a maximum breath out is called the __________
_____________, and is about 1,200 mL. The presence of this residual air means the CO2
concentration in the lungs is always ______________ than the concentration in the air
outside the body.
16. Chemoreceptor in the brain are called ____________ receptors, and respond mainly to
CO2 and pH. Receptors in the carotid arteries and aortic arch, called ____________
receptors, respond to CO2 and O2. Respiratory centers in the __________
_______________ and __________ of the brainstem control the rate and depth of
breathing to maintain homeostasis of CO2, pH, and O2. As CO2 levels increase or blood
pH levels drop below 7.35, respiratory rate will _____________. As CO2 levels decrease
or blood pH levels rise above 7.45, respiratory rate will ____________.
17. Gas exchange takes place in the _____________ of the lungs. The gases, oxygen and
carbon dioxide, move by __________ ___________.
18. In the lungs, oxygen moves from the _____________ to the ___________.
19. In the tissues, oxygen moves from the ___________ to the ____________.
20. Oxygen is carried in the blood bound to _____________ and dissolved in the blood.
21. Carbon dioxide is carried in the blood in ___________ forms: 10% is _____________,
20% is attached to __________________, and 70% is converted to ________________.
22. The enzyme _____________________ _________________, found in RBCs, is
responsible for altering CO2. The resulting ____________ acid breaks down to form
bicarbonate and the ion ________. This process reverses as the blood approaches the
alveoli so that ___________ can be reformed and diffuse out of the blood. It is the

relationship between CO2 and the ion _______ that explains why pH affects respiratory
rates.
23. Because hemoglobin is a protein, its shape and function is affected by factors such as
temperature, pH, and binding of substances. For example, increased CO2 in the blood will
cause a ______________ in oxygen binding at the same oxygen partial pressure because
some CO2 binds to hemoglobin.
