Question

question 1 - 10: in humans, oxygen and carbon dioxide are exchanged between the alveoli in the lungs and the blood in the circulatory system. which of the following processes allows the exchange?
○ osmosis
○ simple diffusion
○ active transport
○ facilitated diffusion

Explanation:

Oxygen and carbon - dioxide exchange between the alveoli in the lungs and the blood in the circulatory system occurs through simple diffusion. This is because there are concentration gradients for these gases, and no energy or transport proteins are required for the movement of oxygen from the alveoli (higher concentration) to the blood and carbon - dioxide from the blood (higher concentration) to the alveoli.

Answer:

simple diffusion
