Question 18

It is responsible for receiving blood from the right atrium.

Answer 18

RIGHT VENTRICLE

Question 19

It is responsible for receiving blood from the left atrium.

Answer 19

LEFT VENTRICLE

Question 20

Answer 20

semilunar valves
atrioventricular valves

Question 21

Pulmonary and Aortic Valves are?

Answer 21

Semilunar Valves

Question 22

located at the entrance of the pulmonary trunk. It prevents blood from moving from the pulmonary trunk into the right ventricle during ventricular relaxation.

Answer 22

Pulmonary Valves

Question 23

It is located at the entrance to the aorta. It prevents blood from moving from the aorta into the left ventricle during ventricular relaxation.

Answer 23

Aortic Valves

Question 24

Tricuspid and Bicuspid Valves are?

Answer 24

Atrioventricular Valves

Question 25

It is located at the right atrioventricular orifice. It prevents blood from moving from the right ventricle into the right atrium during ventricular contraction.

Answer 25

Tricuspid Valve

Question 26

It is located at the left atrioventricular orifice. It prevents blood from moving from the left ventricle into the left atrium during ventricular contraction.

Answer 26

Bicuspid Valve (mitral)

Question 27

pathway of blood through the heart

Answer 27

1) Blood from systemic circuit 2) Blood will now enter Superior and Inferior Vena Cava, and Coronary Sinus 3) Blood enters Right Atrium and tricuspid valve will shut 4) Blood enters Right Ventricle and pulmonary valve, pulmonary trunk and pulmonary arteries which contains deoxygenated blood 5) Blood enters Pulmonary arteries and will supply blood in the heart 6) Blood goes to Alveolar capillaries of lungs, where oxygenation happens 7) Blood will now pass through pulmonary veins containing oxygenated blood 8) Blood will enter Left Atrium then bicuspid (mitral) valve will shut 9) Blood will enter Left Ventricle then aortic valve will shut and then goes to aortic valve and then to aorta 10) Blood will now go to systemic circuit
