Through water. Oxygen can not be transferred out of the lungs and into the blood without passing through water.
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).
Mostly oxygen & carbon dioxide - but also some nitrogen.
The humorus
carbon dioxide and oxygen
The tiny air sacs of the lungs were oxygen and carbon dioxide are exchanged are the alveoli.
diffusion
Alveoli. this is the right answer
Oxygen and carbon dioxide are exchanged at the surface of the air sac. Oxygen is taken in from the air into the bloodstream, while carbon dioxide is released from the bloodstream into the air to be exhaled.
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.
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.
The tiny air sacs in the lungs where oxygen and carbon dioxide are exchanged are called alveoli. They are surrounded by blood vessels through which gas exchange takes place during the process of respiration.
