Gas diffuses from a capillary into the alveolus in the lungs. the gas is expelled out of the alveolus during the exhalation.
Option B
Explanation:
- since the gas diffuses from the capillary into the alveolus in the lungs
- It means that the concentration of the gas is more in the blood capillary as compared to the alveoli since diffusion is the movement of substances from the region of higher concentration to the movement of lower concentration.
- Hence the gas P diffuses and moves out of the body during the exhalation Phase.
