Q

Where does blood flow after the pulmonary veins?

A

left atrium

21
Q

Where does blood flow after the left atrium?

A

mitral (bicuspid valve)

22
Q

Where does blood flow after the mitral valve?

A

23
Q

Where does blood flow after the left ventricle?

A

aortic semilunar valves

24
Q

Where does blood flow after the aortic semilunar valves?

A

aorta

25
Q

Where does blood flow after the aorta?

A

body tissues (systemic circulation)

26
Q

It is the main pacemaker of the heart.

It is located in the right wall just inferior and lateral to the opening of the superior vena cava.

A

Sinoatrial Node (SA)

27
Q

It is located in the interatrial septum, just anterior to the opening of the coronary sinus.

A

Atrioventricular Node (AV)

28
Q

From the AV node, it is where action potentials enters the AV bundle.

The only site where action potentials can conduct from the atria to the ventricles.

A

AV bundle of HIS

29
Q

It rapidly conducts the action potential beg at the apex of the heart, upward to the

A

Purkinje Fibers

30
Q

The artery that supplies the right atrium and most of the right ventricle.

A

Right Coronary Artery

31
Q

The artery that supplies most of the left ventricle.

A

Left Coronary Artery

32
Q

2 main divisions of Left Coronary Artery.

A

Left Anterior Descending and Circumflex

33
Q

Part of the Left Coronary Artery that supplies the left ventricle and the interventricular septum.

A

Left Anterior Descending

34
Q

Part of the Left Coronary Artery that supplies blood to the lateral and inferior walls of the left ventricle and portions of the left atrium.

A

Circumflex

35
Q

It is where the blood flows after it passes through the arteries of the coronary circulation.

A

Coronary Veins

36
Q

Outer protective layer of the heart

A

Epicardium

37
Q

Middle muscular layer of the heart; makes up about 95% of the heart and is responsible for its pumping action

A

Myocardium

38
Q

Thin inner layer of the heart

A

Endocardium

39
Q

Fibrous protective sac enclosing the heart

A

Pericardium

40
Q

4 chambers of the heart

A 
Right Atrium (RA)
Right Ventricle (RV)
Left Atrium (LA)
Left Ventricle (LV)
41
Q

What are the heart valves?

A

Atrioventricular Valve
Tricuspid Valve
Bicuspid Valve

Semilunar Valve
Pulmonary Valve
Aortic Valve

42
Q

Blue color

A

Unoxygenated blood

43
Q
