The arterioles then divide further into capillaries. Capillaries are the smallest blood vessels and their walls are only one cell thick which allows diffusion between the blood and cells to occur. Nutrients and oxygen from the blood diffuses through the capillary walls into the tissues that need it. This is aided by the relatively high blood pressure that also squeezes the oxygen and nutrients through the capillary wall and into the cells of the tissue. At the same time carbon dioxide and other waste products re-enter the capillary in order to be processed and removed from the body.
All three are types of blood vessels. Arteries carry freshly-oxygenated blood away from the heart and supply it to organs and other parts of the body that need oxygen. Veins carry oxygen-depleted blood back to the heart.Capillaries are tiny blood vessels that branch off from arteries and veins, and that most closely interact with tissue to supply oxygen to them (or carry oxygen-depleted blood away from them).Mark H Â· 9 years ago.eins carry oxygen-depleted blood back to the heart.
