20
Q

endocardium

A

lines chambers; thin and smooth

21
Q

pericardium

A

covers heart

loose sack so heart can beat

22
Q

two layers of pericardium

A

visceral

parietal

23
Q

visceral pericardium

A

inner layer

24
Q

parietal pericardium

A

outer layer

25
Q

arteries

A

away from heart

26
Q

veins

A

to heart

27
Q

arterioles

A

small arteries which go to capillaries

28
Q

capillaries

A

1 cell thick

exchange of nutrients and gases

29
Q

venuoles

A

small veins connected to capillaries

30
Q

hepatic portal circulation

A

blood flow through liver
veins from surrounding organs send blood though
remove excess glucose; store as glycogen
remove poisonous substances

31
Q

systole

A

contraction of heart

32
Q

diastole

A

relaxation of heart

33
Q

blood pressure

A

systole

diastole

34
Q

what may plug arteries

A

thrombosis and embolism

35
Q

what happens if thrombosis and embolism plug arteries in heart

A

myocardial infarction

heart attack

36
Q

angina pectoris

A

severe chest pain

37
Q

what surgery do they perform after heart attacks

A

coronary (artery) bypass surgery

38
Q

where do cardiac veins return blood to

A

right atrium

39
Q

conduction system purpose

A

electrical signals that tell heart when to beat

40
Q

stroke volume

A

volume of blood ejected from ventricles during each beat

41
Q

cardiac output

A

volume of blood pumped by one ventricle per minute

42
Q

how much blood is pumped throughout body in a minute

A

5L

43
Q

4 steps to conduction path

A

sinoatrial node
AV node
AV bundle/pundle of his
purkindle fibers

44
Q

why do veins have a one way valve

A

pressure isn’t high enough; keeps blood from going backwards

45
Q

3 layers of blood vessels

A

tunica adventitia
tunica media
tunica intima

46
Q

tunica adventitia

A

outer layer

47
Q

tunica media

A

smooth muscle tissue

48
Q

tunica intima

A

inner layer

49
Q

precapillary sphinclers

A

guard capillaries
