Role Of The Heart
The heart’s main role is to pump blood. In its role as a pump, the main pumping chambers of the heart are located on the left side. Blood comes into the left side of the heart from the lungs, which in turn, pumps the blood to all of the vital organs to the left side of the heart, which in turn, pumps the blood to all of the vital organs, the muscles, the intestines, and everything else in the body that needs blood. The blood then flows back to the right side of the heart. The right side of the heart in turn pumps blood to the lungs and back to the left side of the heart, and the process starts all over again.
The heart works closely with the lungs and together make up the major components of the circulatory system. The heart sits right in the middle of the lung cavity and the lungs itself surrounds the heart. The lungs provide oxygen to the blood and the heart in turns pumps the blood out to the body.
The heart is an amazing organ. Unlike the rest of the muscles, the heart can never stop. The average person has a resting heart rate of between 60 to 75 beats per minute, which means that the must maintain a hundred thousand heartbeats each day.
