Blood within the pulmonary veins returns to the

• left atrium
• left ventricle

• right ventricle

• right atrium

Blood returns to the right atrium by way of the

• coronary arteries

The stroke volume for a normal resting heart rate is _________ mL/beat

• 120
• 90
• 50
• 75

Which of the following is NOT part of the conduction system of the heart?

• Bundle of His

• AV Node

• SA Valve

• SA Node

The atrioventricular valves (bicuspid and tricuspid) close when the

• atria fill with blood
• ventricles relax during diastole
• blood flows from ventricles to atria
• ventricles contract during systole

The SA node is located

• in the interventricular septum
• in the right atrium of the heart
• in the right ventricle of the heart
• in the left atrium of the heart

The second heart sound is created by the

• closure of the aortic and pulmonary valves
• relaxation of the atria
• contraction of the ventricles
• opening of the mitral and tricuspid valves

The first heart sound is caused by the

• closure of the aortic and pulmonary valves

• relaxation of the ventricles
• closure of the bicuspid and tricuspid

• opening of the semilunar valves

The pulmonary arteries carry blood to the

• heart
• kidneys
• lungs
• liver
