Question 6 • 24 - 25 CR - Biology B (0411KB)

Which is the correct pathway of oxygen as it travels from the lungs and goes to the cells of the body?

Answer
A
lungs, goblet cells, cilia, trachea, cells
B
lungs, trachea, alveoli, larynx, cells
C
lungs, bronchioles, alveoli, capillaries, cells
D
lungs, alveoli, bronchi, pharynx, cells

Explanation

Air travels through the smaller airways called bronchioles to reach the alveoli in the lungs. Oxygen then diffuses from the alveoli into nearby capillaries, which carry it through the blood to the body’s cells. So the pathway is lungs, bronchioles, alveoli, capillaries, cells.
