1

cardiovascular system

delivers oxygen and nutrients to cells of body tissue

2

ateries

vessels that lead away from heart

3

arterioles

smaller branches of arteries

4

veins

have thinner walls than arteries and move deoxygenated blood toward the heart from the tissues

5

venules

small veins that carry waste filled blood back to the heart

6

capilleries

smallest vessels
point of exchange for oxygen and nutrients into body cells

7

which blood vessel has a valve

vein

8

diastole

relaxation

9

systole

contractions

10

SA node

pacemaker of the heart

11

pacemaker

origin of electrical impulse causing walls of the atria to contract and force blood into the ventricles

12

AV node

sends excitation wave to a bundle of specialized fibers

13

blood pressure

the force that blood exerts on arterial walls

14

sphygmomanometer

measures blood pressure

15

hypertension

high blood pressure

16

aorta

the largest artery in the body

17

endocardium

inner lining of the heart

18

endothelium

innermost lining of blood vessels

19

murmur

abnormal swishing sound caused by improper closure of heart valves

20

pericardium

double layered membrane surrounding the heart

21
