Question 1

What is the primary mechanism by which oxygen moves from the alveoli into the blood capillaries in the lungs?

Accepted Answer

D. Simple diffusion — Oxygen moves from the alveoli into the blood capillaries by simple diffusion. This process occurs because the partial pressure of oxygen is significantly higher in the alveoli than in the deoxygenated blood within the capillaries, creating a concentration gradient that drives oxygen across the alveolar and capillary membranes. Active transport requires energy and moves substances against a gradient, facilitated diffusion uses carrier proteins, and osmosis is specific to water movement.
