Heart Quick Check 2

(a)   The two receiving chambers of the heart are known as the (b)   , while the two inferior discharging chambers of the heart are called the (c)   .

• Ventricles; atria

• Atria; ventricles

• Atria; veins

• Systemic; pulmonary

(a)   The valve located at the exit point of the left ventricle is known as the (b)   valve.

• Aortic

• Pulmonary

• Atrioventricular

• Semilunar

What is the purpose of pulmonary circulation?

• Delivery of oxygen to body tissues and removal of carbon dioxide

• Delivery of carbon dioxide to the lungs for removal and reoxygenation of the blood

• Transport of white blood cells to the body to start an immune response

• Production of red blood cells

Which blood vessel(s) deliver blood to the left atrium?

• Aorta

• Superior vena cava

• Inferior vena cava

• Pulmonary veins

• Both B and C

Identify the function of the arteries.

• Transport blood away from the heart

• Carry blood to the heart

• Transport oxygen-poor (deoxygenated blood)

• Transport blood to the body’s tissues

What structures in the heart prevent backflow of blood into the ventricles?

• Left and right AV valves

• Aortic and pulmonary valves

• Left AV and aortic valves

• Venous valves

What is the most basic function of the heart?

• Oxygenate the blood when it returns from the systemic circulation

• To pump blood through the pulmonary and systemic circulation

• Remove excess oxygen in blood before it enters the systemic circulation

• Remove nitrogen from the blood prior to the pulmonary circuit
