Alveoli. Singular is alveolus.
Alveoli which are in your lungs
Alveoli which are in your lungs
I believe the tiny blood vessels are called capillaries, located in the lungs.
They are called capillaries.
capillaries
The smallest vessels in the human body are capillaries. They are the blood vessels that absorb oxygen into the blood and returning blood cells that lack oxygen back into the heart and lungs to be oxidised.
Arteries branch off from the heart, which then thin out into capillaries. The capillaries return through veins back to the heart which the oxygen poor blood is replenished with oxygen from the lungs.:D
the air goes into your lungs. In your lungs there are billions of tiny air sacs. Surrounding each air sac is a network of blood capillaries. The air sacs and the blood capillaries are separated by a thin membrane. Across this membrane the air sacs give the blood capillaries oxygen and they blood capillaries give the air sacs carbon dioxide. We breathe out this carbon dioxide!
The lungs are the primary organs that fill blood with oxygen. Oxygen from the air is inhaled into the lungs, where it moves into the bloodstream through tiny blood vessels called capillaries surrounding the lungs' air sacs.
The blood passes through tiny capillaries that lie in close proximity to the alveoli in the lungs. This is where the gas exchange takes place.
The lungs are the organs responsible for filling blood with oxygen. In the lungs, oxygen from the air we breathe diffuses into the blood in the capillaries surrounding the alveoli, which are tiny air sacs in the lungs. This oxygenated blood is then pumped by the heart to the rest of the body.
There are three types of blood vessels; arteries, veins, and capillaries. Capillaries are tiny blood vessels.
