What is the interventricular septum?

Question 14

This wall in the heart separates the right atrium from the left ventricle

Answer 14

What is the right atrio- ventricular septum

Question 15

This wall, within the heart separates the left atrium from the left ventricle

Answer 15

What is the left atrioventricular septum?

Question 16

This structure located in the left ventricle is a series of ridges formed by irregular folds of the mitochondrion in the anterior wall of the ventricle

Answer 16

What is the Trabeculae Carneae?

Question 17

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

Answer 17

What is the chordae tendinae

Question 18

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

Answer 18

What are papillary muscles?

Question 19

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

Answer 19

Question 20

This is the artery where deoxygenated blood leaves the heart

Answer 20

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

Question 21

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

Answer 21

What are pectinate muscles?

Question 22

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

Answer 22

Question 23

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

Answer 23

Question 24

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

Answer 24

What is the inferior vena cava? (IVC)

Question 25

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

Answer 25

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

Question 26

Why does our heart have valves?

Answer 26

To prevent a black flow of blood

Question 27

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

Answer 27

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

Question 28

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

Answer 28

What is the pulmonary semi lunar valve?

Question 29

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

Answer 29

Inside the capillaries of the lungs

Question 30

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

Answer 30

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

Question 31

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

Answer 31

What is the aortic semi-lunar valve?

Question 32

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

Answer 32

What is make the heart beat through small electrical impulses?

Question 33

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

Answer 33

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

Question 34

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.

Answer 34

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

Question 35

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

Answer 35

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

Question 36

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

Answer 36

What is the bundle of His

Question 37

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

Answer 37

What are the Purkinje fibers?

Question 38

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

Answer 38

What is systole

Question 39

The relaxation phase of heartbeat is known as this

Answer 39

What is the diastole

Question 40

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

Answer 40

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

Question 41

This structure is located in both the left and right atrium

Answer 41

What is the pectinate muscle?
