7.

Which of the following statements about the circulatory system is false?

a)

Blood in the aorta is oxygenated.

b)

Blood in the pulmonary vein is oxygenated.

c)

Blood in the pulmonary artery is oxygenated.

d)

8.

Which is the main organ of circulation?

Blood

b)

Heart

c)

Capillary

d)

Blood vessels

9.

How do arteries differ from veins?

a)

Arteries carry blood.

b)

Arteries are thin-walled and are used for gas exchange.

c)

Arteries have thicker wall layers to accommodate the changes in pressure from the heart.
