Cardiovascular Health Quiz

Exercise is important for cardiovascular health because it

• increases blood pressure.

• strengthens heart muscle.

• slows the heartbeat.

• reduces sodium in the blood.

If a person's blood lacked platelets, what process could not take place?

• carrying glucose to cells

• clotting of blood

• transfusing of blood

The function of the atria (atrium) is to

• fatty deposits build up on artery walls.

• some of the heart muscle dies.

Atherosclerosis is a condition in which

• veins experience a buildup of fatty material.

• muscles in capillary walls lose their ability to contract.

• capillaries widen and release too much fluid.

• artery walls thicken as the result of a buildup of fatty materials.

• the rate at which blood flows through the heart

• the speed at which oxygen is returned to blood in the lungs

• the strength of the muscles in the walls of the capillaries
