What is the role of capillaries in the circulatory system?
To carry blood back to the heart
To carry blood away from the heart
To store blood
To connect arteries and veins and allow for exchange of substances
Where does deoxygenated blood from the body enter the heart?

What happens during systole?
The ventricles relax and fill with blood
The heart rests and refills with blood
The atria contract and push blood into the ventricles
The ventricles contract and pump blood into the pulmonary artery and aorta
