The Heart

The Heart

Residing in the upper left part of your thorax is the heart. The heart is the most vital organ in your body as it pumps blood and keeps blood flow going throughout your body. Relying on only the brain for direction, the heart takes good control over many systems in your body, including keeping the blood flowing throughout your veins and body. The pump system works as the heart is a hollow muscular organ in the vertebrates. This allows it to " inhale " blood and send it back out to the body.

Supported by the heart, is the circulatory system. This is both a stabilizing and transport system for the body; controlling both temperature and blood flow. Held within the deepest parts of our cells, the blood is transported throughout the veins of our body, controlling the temperature and ph, making sure the body is always at equilibrium. Bringing back deoxygenated blood to the arteries, the veins run throughout the whole body, keeping the blood flowing to other organs in the body. The arteries, helping along with the heart are types of organs that send the blood to all veins in the body. Arteries are like branches throughout the body, sending direct blood flow from the heart to the body.

The human heart is hollow yet is still split up into four chambers in two pairs, the two upper atria and the two lower ventricles. These four different chambers in the heart take action when the blood is being transferred from the heart to the lungs or deoxygenated blood back to the heart. The right atrium, one of the two atria (plural), collects the deoxygenated blood back to this chamber to re-oxydate it, refilling it with the blood cells with fresh oxygen and drop off the used carbon dioxide. This is done by pumping it throughout the right ventricle. This process called diffusion happens in two stages. The second stage uses the opposing sides of the chambers. The newly pumped oxygenated blood is brought to the left atrium from the lungs, and then sent to the left ventricle, pumping it the new blood refreshed blood cells back to the body and continuing the endless process of the circulatory system.

Controlled and influenced only by itself and nothing else, the heart is made of such tissues as cardiac muscle, enabling it to contract and relax itself without the help of other organs. Based on this fact, it is easy to say that the heart works by a kind of self conducting system
