Arteries
Capillaries are the smallest
of the the body's blood vessels.
They are also one cell thick and they are the sites of the transfer
of oxygen and other nutrients from the blood stream to other tissues in the body.
Veins are very important,they are
responiblefor returning our
deoxygenated blood back to the
heart after arteries carry blood
out.
Arteries are blood vessels that
carry blood away from the heart.
Blood carried by arteries are usually
highly oxyegenated having just left
the lungs on its way to the body's
tissues.
