Blood vessels

transports blood to and from all areas of the body

Arteries

transport blood AWAY from the heart to all parts of the body

Veins

return blood from all body parts TO the heart

Capillaries

permit exchange of nutrients and waste products between blood and the cells

Blood

brings oxygen and nutrients to the cells and carries away waste

Veins

Has valves, thinner muscular walls, carries deoxygentated blood to the heart

Arteries

No valves, thicker muscular walls to control blood pressure, carries oxygenated blood to the rest of the body

Epicardium

external layer of the heart

Myocardium

middle and thickest of the heart’s three layers, special muscle tissue capable of constant contraction and relaxation, creates the muscle movement needed to pump blood.

Endocardium

inner lining of the heart, comes into direct contact with the blood
