1

Auricle

External wrinkled flap of atrium

2

Base

Top

3

Apex

Bottom

4

Semilunar valve

Aortic pulmonary

5

Atrioventricular valves

Bicuspid

6

Bicuspid valve

Left side

7

Tricuspid valve

Right side

8

Mitral valve

Same as the bicuspid

9

Artery

Away

10

Vein

Toward

11

Foramen ovale

Fetal circulation opening in right atrium

12

Fossa oval is

Remnant of ovale

13

Passageway between Palm. Artery and aorta

Ligamentum arteriosum

14

Remnant of ductus

Ductus arteriosus

15

Muskie in atria and wall

Pectinate m

16

M that closes AV valves

Papillary m

17

M on ventricular walls

Trabeculae carneae

18

Opening in right atrium returns CO2 rich blood to Ruhr atrium

Coronary sinus

19

Indentation that separates atria from ventricle, externally

Coronary sulcus

20

How do atrioventricular valves open

Chordae tendineae and papillary m. Relax

21

Semilunar valves open

Force of blood

22

Right atrium receives blood from the

Superior and inferior vena cava

23

Oxygenated blood is delivered to the surface of the myocardium by the

Coronary arteries

24

Endocardium

Squamous c.t. Lining the chambers and valves

25

Epicardium

Same as visceral pericardium

26

Myocardium

Same

27

Parietal pericardium

Outermost layer

28

Visceral pericardium

Innermost layer

29

Serous pericardium

Parietal and visceral combined

30

What's the average pulse for a healthy adult? Average blood pressure

70 Bpm
120/80 mmHg

31

Systemic circulations

Heart body heart

32

Pulmonary circulation

Heart lung heart

33

Coronary circulation

To heart muscle, itself

34

What does the ductus arteriosus close? What purpose does it serve in the fetus?

With 1st breath that the baby takes, by-passes the fetal lungs during development

35

When does the foremen ovale close? What purpose does it serve in the fetus?

A few days/weeks after birth. By-passes fetal lungs

36

Pericarditis

Inflammation of pericardium- usually a viral infection

37

Compression of the heart due to build up of fluid or blood around it is called

Cardiac tamponade

38

Cpr

Cardiopulmonary resuscitation

39

MVp

Mitral valve prolapse

40

What is wrong with a blue baby

Cyanosis- can be due to blood flow between the right and left atrium

41

Rheumatic fever can permanent damage heart valves. What causes it?

Viral infection

42

Valve replacements come from

Pig or cow

43

What is a heart attack

Heart stops beating then a infarete occurs if there is dance or scaring to the muscle

44

Systole

Amount of force when heart muscle contracts

45

Diastolic

Heart relaxed

46

Myocardial infarction

Heart attack, can leave behind a dead area called an infarete

47

Aneurism

Weakening or bulging of an artery

48

Atherosclerosis

Build up of fat inside arteries, plaque which restricts blood flow

49

Arteriosclerosis

Hardening of artery walls

50

Lubb

Av valves closing

51

3 pulse points

Carotid, radial, femoral

52

Murmur

aV valve doesn't close completely. Usually bicuspid

53

Semilunar valve

Pulmonary and aortic, at exits of the heart, close due to lack of blood pushing against the valve

54

Arteries always go

Away

55

Veins always go

Toward

56

Atrioventricular

Bicuspid and tricuspid, attached by strings to papillary muscles

57

Atrium

Upper chamber
