Circulatory System Quiz

What would happen if the heart stopped working in the circulatory system?

• Blood would continue to circulate normally

• Blood would not be transported to the body

• Oxygen would be produced in the body

• Nutrients would be digested faster

Which chamber receives oxygen-rich blood from the lungs?

• Right Atrium

• Left Atrium

• Right Ventricle

• Left Ventricle

Why is the left ventricle considered the strongest chamber of the heart?

• It collects deoxygenated blood from the body

• It generates high pressure to counter systemic resistance

• It acts as a reservoir for deoxygenated blood

• It delivers blood to the lungs for oxygenation

What happens to blood in the right ventricle before it returns to the left side of the heart?

• It is oxygenated in the body tissues

• It is expelled from the body

• Carbon dioxide is expelled and oxygen is absorbed in the lungs

• It is stored in the right atrium

Through which valve does blood pass from the right ventricle to the pulmonary artery?

• Aortic valve

• Tricuspid valve

• Pulmonary valve

• Mitral valve

What would be the effect if the pulmonary artery carried oxygenated blood instead of deoxygenated blood?

• The body would receive less oxygen

• The lungs would not oxygenate the blood

• The heart would stop pumping

• The right ventricle would enlarge

Which side of the heart is described as receiving oxygenated blood from the lungs?

• Right side

• Both sides

• Left side

• Neither side

Which statement best describes the role of the left atrium in blood circulation?

• It pumps blood to the lungs.

• It receives oxygenated blood from the pulmonary vein.

• It filters blood before it enters the body.

• It stores deoxygenated blood.

Why is it important for blood to be pumped from the left ventricle into the aorta?

• To supply oxygenated blood to the lungs

• To supply oxygenated blood to the entire body

• To remove waste from the heart

• To regulate heart rate

Which type of blood vessel carries blood away from the heart?

• Arteries

• Veins

• Capillaries

• Lymphatic vessels
