| What is the function of: artery, vein, capillary, venule, arteriole? |
|
Definition
artery: carry oxygenated blood away from heart to body
vein: return deoxygenated blood back to heart to be oxygenated
capillary: bring nutrients and oxygen to tissues and remove waste products
venule: small b.v. that allows deoxygenated blood to return from capillary beds to larger veins
arteriole: controlled by sympathetic n.s., constrict and dialate to regulate blood flow. transport blood from arteries to capillaries |

Term
| How is the wall of an artery different from the wall of a vein? What is the function of a valve? |
|
Definition
an artery has a thicker tunica media compared to the tunica media of a vein and a vein has a valve.
the valve keeps blood moving in one direction: back to the heart |
