What is called a tiny vessel?

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.


Are capillaries tiny blood vessels that connect arteries to veins?

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


What is the name of the organ that you use to breathe in oxygen?

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!


If blood takes in oxygen and releases carbon dioxide in the lungs the blood passes through what?

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.


What organs that fill blood with oxygen is?

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 organs that fill blood with oxygen?

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.


What are tiny air sacs surrounded by blood capillaries?

Tiny air sacs surrounded by blood capillaries are called alveoli. They are the primary site of gas exchange in the lungs, where oxygen from the air is absorbed into the blood, and carbon dioxide is released from the blood to be exhaled. Each alveolus is surrounded by a network of capillaries, facilitating this crucial exchange between the respiratory and circulatory systems.
