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.

An artery that is patent is an open tube. Blood will not flow through a closed tube.
Arteries are blood vessels taking the blood away from the heart. the heart is a very powerful muscle so blood is ejected out at a high velocity and with high pressure.
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.
