TOPIC 1: RESPIRATORY MECHANICS
10 Questions • 16.1% of Exam • This topic covers the physiological processes of breathing and lung function.
QUESTION 1
Expiration is an active process, whereas inspiration is largely passive?
Correct Answer: False.
Rationale: The statement is incorrect because expiration is also largely a passive process, as it involves the elastic recoil of
the lungs and the airways, rather than an active process requiring muscle contraction. The primary active process involved
in breathing is inspiration, which requires the contraction of the diaphragm and intercostal muscles to expand the lungs and
draw air in.
QUESTION 2
Both carbon dioxide and oxygen are able to bind with hemoglobin?
Correct Answer: True.
Rationale: Carbon dioxide binds to hemoglobin through a process called carbaminohemoglobin formation, where carbon
dioxide combines with the amino groups of the hemoglobin molecule. Oxygen also competes with carbon dioxide for these
binding sites, but hemoglobin's affinity for oxygen is greater than its affinity for carbon dioxide, allowing it to release oxygen
to tissues while binding carbon dioxide for transport.
QUESTION 3
There are _____ in the actual sites of gas exchange between the air and blood
Correct Answer: Alveoli.
Rationale: The correct answer is "alveoli" because they are tiny sacs located at the end of the bronchioles in the lungs
where oxygen from the air diffuses into the bloodstream and carbon dioxide diffuses out, facilitating gas exchange. This
process is essential for the respiratory system to function properly, enabling the body to receive oxygen and remove carbon
dioxide.
