Circulation and Cardiac Cycle Quiz

What is the primary function of pulmonary circulation?

• To deliver oxygenated blood to the body

• To remove carbon dioxide from the blood and oxygenate it

• To transport nutrients to cells

• To regulate body temperature

Which chamber of the heart receives deoxygenated blood from the body?

• Left atrium

• Right atrium

• Left ventricle

• Right ventricle

In systemic circulation, where does the oxygenated blood go after leaving the left ventricle?

• To the lungs

• To the right atrium

• To the aorta

• To the pulmonary artery

What is the correct order of the cardiac cycle phases?

• Atrial systole, ventricular systole, diastole

• Ventricular systole, atrial systole, diastole

• Diastole, atrial systole, ventricular systole

• Atrial systole, diastole, ventricular systole

During which phase of the cardiac cycle does the heart fill with blood?

• Atrial systole

• Ventricular systole

• Diastole

• Isovolumetric contraction

What is the main artery that carries blood from the heart to the rest of the body in systemic circulation?

• Pulmonary artery

• Coronary artery

• Aorta

• Carotid artery

Which blood vessels carry deoxygenated blood from the heart to the lungs?

• Pulmonary veins

• Pulmonary arteries

• Coronary arteries

• Aorta

What happens during atrial systole?

• The atria contract and push blood into the ventricles

• The ventricles contract and push blood into the arteries

• The heart relaxes and fills with blood

• The heart valves close

Which side of the heart is responsible for pumping blood to the lungs?

• Left side

• Right side

• Both sides

• Neither side

What is the role of the pulmonary veins in circulation?

• To carry deoxygenated blood to the lungs

• To carry oxygenated blood from the lungs to the heart

• To carry blood from the heart to the body

• To carry blood from the body to the heart
