Central Retinal Artery
There are two blood vessels that take the blood away from the heart. The PULMONARY ARTERY takes deoxygenated blood from the heart to the lungs to get oxygenated, and the AORTA which takes oxygenated blood from the heart and distributes it to the body.

The heart is a four chambered muscular pump, whose sole purpose is to (hopefully) pump blood round the circulatory system. There is only one heart!
gorillas have a heart with 4 chambers and a blood system that uses hemoglobin
Unless stopped by "outside forces" the heart will continue to beat on at a quick enough rate to force blood through the body. If that blood were to stop, even for a few seconds, the effects could be devastating. Blood makes possible many of the bodily processes necessary to live, including breathing. The heart without any disturbances of that "outside" nature (leave you to imagine what out of many possibilities could cause a heart to stop) will always beat on at a fast rate so that no part of the body goes without the very life essense of humans, blood.
