Cardiovascular System - Heart Quiz

Explain the role of the atria in the heart's function.

• The atria pump blood to the body and lungs

• The atria regulate blood pressure in the heart

• The atria store blood for future use

• The atria receive blood from the body and lungs and then pump it into the ventricles.

How does the heart maintain blood pressure in the body?

• By pumping blood through the arteries and regulating the force of the blood flow.

• By controlling the amount of oxygen in the blood

• By releasing hormones into the bloodstream

• By filtering the blood through the kidneys

What is the main function of the heart?

• To digest food

• To regulate body temperature

• To pump blood throughout the body

• To produce hormones

Describe the function of the ventricles in the heart.

• Regulating body temperature

• Digesting food

• Producing hormones

• Pumping blood to the lungs and the rest of the body

Explain the pathway of blood flow through the heart.

• Right atrium, right ventricle, pulmonary artery, lungs, pulmonary veins, left atrium, left ventricle, aorta

• Right atrium, right ventricle, aorta, lungs, pulmonary veins, left atrium, left ventricle, pulmonary artery

• Left atrium, right ventricle, pulmonary artery, lungs, pulmonary veins, right atrium, left ventricle, aorta

• Right atrium, left ventricle, pulmonary artery, lungs, pulmonary veins, right ventricle, left atrium, aorta

What is the function of the pulmonary artery in the heart's blood flow?

• Carries deoxygenated blood from the heart to the lungs

• Carries blood from the heart to the rest of the body

• Has no function in the heart's blood flow

• Carries oxygenated blood from the lungs to the heart

Describe the role of the atrioventricular valves in the heart's blood flow.

• They prevent the backflow of blood from the ventricles to the atria.

• They transport oxygen to the body

• They regulate the heart rate

• They control the blood pressure

How does the heart ensure the separation of oxygenated and deoxygenated blood in its blood flow?

• Through the use of special filters

• Different chambers and valves

• By using different colors of blood

• The heart doesn't separate oxygenated and deoxygenated blood

Explain the function of the aorta in the heart's blood flow.

• It carries deoxygenated blood from the body to the heart.

• It is responsible for regulating the heart rate.

• It carries oxygenated blood from the heart to the rest of the body.

• It transports nutrients from the small intestine to the rest of the body.

How does the heart respond to increased physical activity?

• It slows down the heart rate.

• It increases the heart rate to pump more blood to the muscles.

• It decreases the amount of blood pumped to the muscles.

• It does not respond to physical activity.
