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

Why is resting heart rate important for cardiac health and what does it indicate about fitness level?

Explain how the pulmonary and systemic circuits work together to regulate oxygen and carbon dioxide levels in the body.
