Binding carbon fioxide
Releasing oxygen
The thin walled blood vessels are called capillaries.
Platelets are cell fragments that prevent blood from leaking through capillaries
Arteries feed into capillaries, the capillaries give oxygen and nutrients to every cell in the body and take toxins and CO2 from every cell in the body, from there the blood in the capillaries go into your veins (the blue blood vessels) which go to your heart.
The function of the capillaries is to distribute oxygen carried on the hemoglobin of the red cells to all the cells of the body. The blood also carries nutrients to all the cells of the body. Blood comes to the capillaries through the arteries, then is sent back to the heart via the veins. Capillaries are also the waste disposal system for the cells of the body. Water, carbon dioxide, and other wastes are uploaded to the blood to be disposed of in the kidneys, lungs and liver.

The smallest blood vessels are the capillaries.
A pericyte is a type of cell that is found in the walls of capillaries and small blood vessels. They play a role in blood vessel formation, stability, and regulation of blood flow. Pericytes also have functions in tissue repair and maintenance.
they are only one blood cell thick!
From the blood to the cell.
