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 for the exchange of these gases in the human body? osmosis

simple diffusion

active transport

facilitated diffusion

Simple diffusion

Explanation:

Diffusion is a process in which material travels from regions of high concentration to low concentration until equilibrium is reached. Gas molecules move from a region in which they are at high concentration to one in which they are at low concentration. Diffusion is a passive process, meaning that no energy is required to power the transport, and it follows Fick's Law
