From the arteries, the blood flows into the capillaries where food and oxygen diffuse through the one-cell-thick capillary walls and into the cells. Carbon dioxide and cellular wastes then diffuse into the blood. The capillaries then form veins. The veins then lead back to the heart so the blood can be sent to the lungs to be oxygenated. The blood is then pumped through the arteries to the rest of the body again.
5] left coronary artery and right coronary artery
After blood is distributed through a capillary bed, it is collected in the venules which eventually join up to create veins that drain into the right side of the heart.

An artery that is patent is an open tube. Blood will not flow through a closed tube.
atherosclerosis
Blood flows away from the heart and is measured as blood pressure. This is a measure of the passage or flow and the resistance of the flow in the arteries.

Maintaining blood pressure.
Clots may form in theses narrowed arteries and block blood flow high blood cholesterol levels can cause hardening of the arteries at a younger age.
