1

endocardium

inner linning of the heart

2

myocardium

heart muscle

3

epicardium

top layer of the heart

4

pericardium

sac holding the heart

5

atria does what?

receives the blood

6

what does the right atria do?

deoxygenated blood from venae cavae

7

what does the left atria?

oxygenated blood from the lungs

8

what do the ventricles do?

pump blood from the heart

9

what does the right ventricle do (pulmonary circulation)?

pumps blood to lungs for oxygenation

10

what does the left atria do (systemic circulation)?

pumps blood through the aorta to the body systems

11

what do heart valves prevent?

backflow; regurgitation of blood

12

tricuspid valve:

from right ventricle into right atrium

13

bicuspid (mitral) valve:

from the left ventricle into the left atrium

14

pulmonic valve:

from the pulmonary artery into right ventricle

15

aortic valve:

from aorta into left ventricle

16

arteries do what and carry what (strong muscular wall)?

carry blood away from the heart; and carry oxygenated blood

17

capillaries:

join arterial system; have thin walls to allow exchange of blood and body tissues; vessels composed of endothelial cells

18

what do the veins do and what does it carry (contain valves to return blood)?

carry blood to the heart; carry deoxygenated blood

19

what is the main function of the heart?

To propel blood for the transport of respiratory gases, nutrients, wastes, and immune substances in the body

20

what structures prevent backflow of blood?

Heart valves—the bicuspid, tricuspid, aortic valve, and pulmonic valve

21

list the tree major types if blood vessels and the function of each?

Arteries carry blood away from the heart; veins carry blood to the heart; capillaries join the arterial system with the venous system.

22

Which blood vessels contains valves? why?

Veins possess valves to prevent backflow of blood because it commonly must travel against gravity to return to the heart.

23

list four chambers of the heart?

Right atrium, right ventricle, left atrium, left ventricle

24

How are the pulmonary artery and pulmonary vein different from other arteries and veins of the body?

The pulmonary artery carries deoxygenated blood; the pulmonary vein carries oxygenated blood.

25

heart:

cardio

26

atrium:

atrio

27

ventricle:

ventriculo

28

septum:

septo

29

vein:

phlebo

30

artery:

aterio
