diffusion
Oxygen is exchanged from the air in the alveoli into the blood in the capillaries, while carbon dioxide is exchanged from the blood in the capillaries into the air in the alveoli during the process of respiration.
oxygen and carbon dioxide are exchanged in alveoli (singular alveolus).
The tiny air sacs of the lungs were oxygen and carbon dioxide are exchanged are the alveoli.
Alveoli
Oxygen diffuses from the alveoli into the capillaries, where it binds to hemoglobin in red blood cells for transport to tissues. Carbon dioxide diffuses from the capillaries into the alveoli and is exhaled from the body.
Mostly oxygen & carbon dioxide - but also some nitrogen.
The alveoli are at the end of the respiratory tree and is where oxygen and carbon dioxide are exchanged between the lungs and the blood.
The humorus
carbon dioxide and oxygen
Oxygen (O2) is exchanged for carbon dioxide (CO2) in the lungs. In the alveoli, tiny air sacs in the lungs, oxygen from the air is transferred into the bloodstream while carbon dioxide from the blood is released into the air to be exhaled.
Alveoli. this is the right answer
Oxygen diffuses from the alveoli of the lungs into the blood. Carbon dioxide diffuses from the blood into the alveoli of the lung where is will be exhaled.
