- The heart layers Endocardium is the inner layer of the heart lining the heart chambersMyocardium – is the thick muscular middle layer of the heart is Epicardium- is the outer layer of the heartPericardium is the inner layer of the sacParietal pericardium is the outer layer of the sac
- Heart= pumps blood through blood vesselsArtery= carries blood away from the heartVein=carries blood toward the heartCapillaries= exchange sites between blood and tissuesOxygenated blood= the systemic circulation carries oxygenated blood away from the heart to the tissues and cells and then back to the heartDeoxygenated= blood in the vein that is low in oxygen Pulmonary circulation transports deoxygenated blood from the right side of the heart to the lungs where oxygen and carbon dioxide are exchangedOxygen=gaseous element absorbed by the blood from the air sacs in the lungs Systemic circulation= transports oxygenated blood from the left side of the heart to the calls of the body and then back to the right side of the heartBlood vessels= there are three types of blood vessels: arteries, capillaries, and veins these are the pipes that’s circulate blood through out the bodyCarbon dioxide= a waste product of cellular energy production. It is removed from the cells by the blood and eliminated from the body by the lungs
- Heart Valves= there are four heart valves
- The cardiovascular system consists of the pump and vessels that distribute blood to all areas of the body .The system allows for the delivery of needed substance to the cells of the body as well for the removal of wastes. The human body could not function without the most important organ the heart. There are other organ in the cardiovascular system ,blood vessel ,arteries, capillaries veins, and the heart
