Circulatory System Quiz

What is the primary function of arteries?

• Carry oxygen-poor blood to the heart

• Connect veins to capillaries

• Carry oxygen-rich blood away from the heart

• Remove waste from cells

Which blood vessels exchange oxygen and nutrients with body cells?

• Arteries

• Veins

• Capillaries

• Pulmonary vessels

How do veins differ from arteries?

• Veins carry oxygen-rich blood, while arteries carry oxygen-poor blood.

• Veins connect to capillaries, while arteries do not.

• Veins have valves to prevent backflow; arteries do not.

• Veins transport blood to organs; arteries transport blood to the heart.

What is the purpose of the pulmonary circuit?

• Supply nutrients to the heart

• Remove carbon dioxide and oxygenate the blood

• Transport oxygenated blood to body cells

• Balance the body's fluid levels

Which of the following is NOT a function of the circulatory system?

• Regulation of body temperature

• Circulation of immune cells

• Exchange of gases with the environment

• Delivery of oxygen and nutrients to cells
