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.
