Left ventricle

19

The cardiovascular system consists of what?

heart, blood and all blood vessels

20

This is the body's pump which circulates blood throughout the body via the blood vessels.

The heart

21

This is the pointed inferior portion of the heart.

Apex

22

This is the superior portion of the heart where the blood vessels enter and leave.

Base

23

This is the connective tissue "sack" that contains and protects the heart. Its a serous membrane, secreting serous fluid to reduce friction and prevent sticking.

Pericardium

24

This layer of the pericardium covers the surface of the heart and is also known as the epicardium.

Visceral pericardium

25

This layer of the pericardium is the most outer.

Parietal Pericardium

26

This is an inflammation of the pericardium.

Pericarditis

27

This layer of the heart is the muscle layer and is composed of cardiocytes.

Myocardium

28

In the myocardium, the cardiocytes (heart cells) are connected by what?

intercalated discs

29

This layer of the heart is the most inner lining, of the chambers of the heart and continuous into the blood vessels. Its made of simple squamous epithelium.

Endocardium

30

This kind of circulation has blood flow from the heart to lungs and back for oxygenation.

Pulmonary circulation

31

This kind of circulation has blood flow from heart to body and back.

Systemic circulation

32

This kind of circulation has blood flow from the muscle tissues of the heart.

Coronary circulation

33

These are the lower chambers of the heart.

Ventricles

34

These are the upper chambers of the heart.

Atria

35

This is the wall that divides the atria.

Interatrial septum

36

This vein is both superior and inferior, brings deoxygenated blood from the body to the right atrium.

Superior and Inferior Vena cava

37

These veins bring oxygenated blood from the lungs to the left atrium.

Pulmonary veins

38

This takes oxygenated blood from the left ventricle to the body.

Aorta

39

This takes deoxygenated blood from the right ventricle to the lungs.

Pulmonary trunk

40

These are 'flaps' on the outside of the atria, they allow the atria to expand.

Auricles

41

This is the valve between the right atria and ventricle, ensures one-way flow of blood.

Tricuspid valve

42

This is the valve between the left atria and ventricle, ensures one-way flow of blood.

Bicuspid valve

43

This is the valve between the left ventricle and aorta, it ensures a one-way flow of blood.

Pulmonary semilunar valve

44

This is the muscle ridges lining the atria.

Pectinate muscles

45

In fetal development, this is what allows the blood to bypass the lungs. After birth, it closes leaving a depression.

Fossa (foramen) Ovalis

46

This literally means "heart strings". They anchor the valves to the ventricle wall to ensure that they don't invert during ventricular contractions.

Chordae tendinea

47

This is the muscle to which the chordae tendonae anchor.

Papillary muscle

48

This is the band of muscle that allows electrical signals to pass from the interventricular septum to the muscle of the right ventricle.

Moderator band

49

One complete heartbeat is known as what?

cardiac cycle

50

The contraction phase of a chamber is what?

Systolic

51

The relaxation phase of a chamber is what?

Diastole

52

The heart sound that a heart beat gives off is commonly reffered to as what?

Lub Dub

53

The "Lub" of the heart beat is when what happens?

closure of the AV valves

54

The "Dub" of the heart beat is when what happens?

Closure of the semilunar valves

55
