right atrium, right ventricle, left atrium, left ventricle

Question 4

What does the right side of the heart do?

Answer 4

Pump for pulmonary circuit

Question 5

What does the right atrium do?

Answer 5

receives deoxygenated blood

Question 6

What does the right ventricle do?

Answer 6

discharges deoxygenated blood into the pulmonary circuit

Question 7

What does the left side of the heart do?

Answer 7

pump for systemic circuit

Question 8

What does the left atrium of the heart do?

Answer 8

receives oxygenated blood

Question 9

What does the left ventricle of the heart do?

Answer 9

discharges oxygenated blood into the systemic circuit

Question 10

The right atrium receives deoxygenated blood from what?

Answer 10

1. Superior vena cava
2. Inferior vena cava
3. Coronary sinus

Question 11

The left atrium receives oxygenated blood from what?

Answer 11

1. Four pulmonary veins (2 right and 2 left pulmonary veins)

Question 12

What are the layers of the heart from superficial to deep?

Answer 12

1. Epicardium
2. Myocardium
3. Endocardium

Question 13

What are the great vessels of the heart?

Answer 13

1. Superior Vena Cava
2. Inferior Vena Cava
3. Pulmonary veins
4. Pulmonary trunk & arteries
5. Aorta

Question 14

What does the superior vena cava do?

Answer 14

SVC is formed by the joining of left and right brachiocephalic vein and returns blood from thoracic wall, upper limb, head and neck.

Question 15

What does the Inferior Vena Cava do?

Answer 15

Formed by the joining of the left and right common iliac vein and returns blood from the abdomen, pelvis, and lower limb.

Question 16

What does the pulmonary trunk and artery do?

Answer 16

Pulmonary trunk leaves the right ventricle and bifurcates into the left and right pulmonary artery

Question 17

What do the four pulmonary veins do?

Answer 17

Pulmonary veins carry oxygenated blood from the lungs to the left atrium

Question 18

What does the aorta do?

Answer 18

Leaves the left ventricle to send oxygenated blood to systemic circulation

Question 19

What does the Atrioventricular valve do?

Answer 19

prevent back flow into atria

Question 20

What are the two types of atrioventricular valves?

Answer 20

Tricuspid valance and Bicuspid (mitral) valve

Question 21

Where is the Tricuspid valve?

Answer 21

Between right atrium and right ventricle

Question 22

Where is the Bicuspid (mitral) valve?

Answer 22

Between left atrium and left ventricle

Question 23

What does the Semilunar valve do?

Answer 23

Prevent back flow into ventricles

Question 24

What are the two types of semilunar valves?

Answer 24

Aortic semilunar valve and pulmonary semilunar valve

Question 25

Where is the Aortic semilunar valve located?

Answer 25

Between left ventricle and aorta

Question 26

Where is the Pulmonary Semilunar Valve located?

Answer 26

Between right ventricle and pulmonary trunk
