Answer to Question 1

Correct Answer: 1,3,4,5
Rationale 1: Ventilation is the process of moving air into and out of the lungs.
Rationale 2: There is no smooth muscle in the alveoli.
Rationale 3: The blood stays in capillaries. A thin membrane separates airway from capillary.
Rationale 4: Perfusion is the blood flow through the lungs. Without this blood flow, the oxygencarbon dioxide exchange does not take place.
Rationale 5: The rate is determined by neurons in the brainstem and can be affected by a number of factors.

Answer to Question 2
