Q: What is the primary site of gas exchange?—ANSWER--A: Alveoli.
Q: What controls the rate and depth of respiration?—ANSWER--A: The medulla oblongata
and chemoreceptors (monitor CO₂, O₂, and pH).
Q: Define ventilation.—ANSWER--A: The movement of air into and out of the lungs.
Q: Define perfusion.—ANSWER--A: The flow of blood through the pulmonary capillaries for
gas exchange.
Q: What is a ventilation-perfusion (V/Q) mismatch?—ANSWER--A: A condition where air and
blood flow in the lungs are not properly matched, impairing gas exchange.
Q: What are common causes of a V/Q mismatch?—ANSWER--A: Pulmonary embolism,
pneumonia, COPD.
Q: What causes asthma?—ANSWER--A: Hypersensitivity reactions leading to
