Answer 1

Answer:

The heart is the heart of the body. It ensures that blood and oxygen is pumped throughout the body. Despite being a little bit larger than a grapefruit, it is one of the most important parts of the body. It weighs eight to twelve ounces depending of the person’s gender (Lewis, 2016). When deoxygenated blood is pumped into the right ventricle of the heart from the body, it is then moved into the pulmonary artery which pumps the blood to the lungs. Inside the lungs, the blood becomes filled with oxygen. This oxygen rich blood is pumped to the left atrium through the pulmonary vein. The blood then moves through the left ventricle and then the aorta where it leaves the heart and is distributed throughout the body, thanks to the arteries and veins, ensuring that the tissues it feeds remain healthy. If the heart didn’t do this function all the tissues in the body will die. These tissues need the oxygen to survive and the blood also carbon dioxide as well as other wastes from the tissues. If the heart suddenly stopped pumping blood, this is called “Sudden Cardiac Arrest” (Texas Heart Institute, n.d.). This occurs three hundred thousand times a year, and when it does ninety five percent of the victims die within minutes. Typically, when this occurs, the patient will faint and stop breathing. The heart will need to be restarted to ensure for no loss of life. The heart is conveniently located in the chest, behind the ribs. Usually it in on the patients left side, however in rare situations, as usually seen on TV or movies, the heart can be on the other side of the chest. In the rest of this essay I will be reviewing the tissue types found in the heart and why the heart requires special tissues, cell types found only in the heart and how the heart needs the cells to function properly, and why the heart requires multiple different cell types to fulfill the roles required of it.
