Q

This fibrous cords that attach to the undersurface of valves to the papillary muscles.

A

What is the chordae tendinae

18
Q

These fingerlike, cone-like muscles project into the lumina of the ventricle

A

What are papillary muscles?

19
Q

This is a large artery where the oxygenated blood leaves the heart

A

What is the ascending aorta?

20
Q

This is the artery where deoxygenated blood leaves the heart

A

What is the pulmonary artery a.k.a. pulmonary trunk?

21
Q

These are muscular ridges that run parallel to each other within the left atrium of the heart

A

What are pectinate muscles?

22
Q

Located in the posterior wall of the right atrium. This vein returns the oxygenated blood from coronary circulation.

A

What is the coronary sinus? 

23
Q

This large vein returns, deoxygenated blood to the heart from all the areas superior to the diaphragm

A

What is the superior vena cava? (SVC)

24
Q

This large vein return, deoxygenated blood to the heart from all the areas of the body inferior to the diaphragm.

A

What is the inferior vena cava? (IVC)

25
Q

This oval depression is located in the inferior aspect of the interatrial septum, the right, and left atria 

A

What is the Fossa Ovalis a.k.a. Fosse Ovale

26
Q

Why does our heart have valves?

A

To prevent a black flow of blood

27
Q

Once the deoxygenated blood returns to the right atrium, it travels through this valve into the right ventricle

A

What is the tricuspid valve a.k.a. the right atrioventricular valve

28
Q

Once the blood is in the right, ventricle, it travels through this valve, allowing deoxygenated blood to flow from the right ventricle into the pulmonary trunk

A

What is the pulmonary semi lunar valve?

29
Q

The pulmonary trunk will bring the oxygenated blood to the lungs, but once inside the lungs, the deoxy blood is exchanged where?

A

Inside the capillaries of the lungs

30
Q

Once in the left atrium, the oxygenated blood travels through this valve into the left ventricle

A

What is the bicuspid valve a.k.a. the mitral valve….

31
Q

The oxygenated blood within the left ventricle, then flows through this valve into the ascending aorta

A

What is the aortic semi-lunar valve?

32
Q

The cardiac cycle system, a.k.a. conduction system has this function to make the heart beat

A

What is make the heart beat through small electrical impulses?

33
Q

The cardiac cycle system, a.k.a. conduction system is composed of how many cardiac muscle fibers

A

What are four cardiac muscle fibers:
1. the sinoatrial node sa node 2 the atrioventricular node aka av node 3. The bundle of His, and 4 the purkinje fibers

34
Q

This node initiates the cardiac cycle by making an electrical impulse that causes the atria to contract, and is considered a pacemaker of the heart.

A

What is the sinoatrial node a.k.a. SA node (considered the pacemaker of the heart)

35
Q

This node pics up the electric impulse from the SA node and delivers it to the bundle of His, and is considered to be the receiving station of the heart

A

What is the atrioventricular node a.k.a. AV node

36
Q

This bundle carries the electric impulses from the SA node down the interventricular septum to purkinje fibers

A

What is the bundle of His

37
Q

This group of fibers emerge from the bundle of His, the electric impulses shoot through these fibers until they reach the apex of the heart, causing the ventricles to contract

A

What are the Purkinje fibers?

38
Q

The contractions phase of the heart pump is known as this?

A

What is systole

39
Q

The relaxation phase of heartbeat is known as this

A

What is the diastole

40
Q

These 3 structures within the heart are located in both the left and right ventricle.

A

What are the
1. chordae Tendinae
2. Papillary muscles
3. Trabeculae Carnae

41
Q

This structure is located in both the left and right atrium

A

What is the pectinate muscle?
