These create the top put ups or the atrium (atria in plural) and the bottom chambers or the ventricles (Sherwood, 2012). The atrium is considered as a holding chamber, and the pumping chambers are the ventricles. exchangeable the names suggests, each of the halves creates a separate system that has to work in sync for one to continue living healthily. Blood flows to the ventricles from the atria and never across the halves, give thanks to the septum (Solomon, Berg and Martin, 2010). For effective flow of melody from the top chambers to the bottom chambers, openings called valves are present. They operate like trapdoors as they allow blood flow just in one direction to avoid a situation where blood would flow back to the atrium. These valves are not only present inside the walls separating the chambers, scarce also on the large arteries that are responsible for the mobing of blood to the organs from the heart. These arteries are the pulmonary arteries and the aorta. While still at it, it is necessary to note that the pulmonary artery is the only artery that carries deoxygenated blood while the other arteries carry oxygenated blood (Solomon, Berg and Martin, 2010). ... Several capillaries form veins, which in turn form larger veins that empty blood into the heart and the cycle continues. This is called blood circulation (Sherwood, 2012). The main aim of blood circulation is to supply oxygen-rich blood to all the organs and tissues in the body. This happens in devil cycles. The first one is a systematic cycle where blood is transported to every section of the body, and carbon dioxide is self-contained amongst other waste from these areas. The pulmonary cycle circulates blood to the lungs and from it to aid in the release of carbon dioxide and bring in oxygenated blood. The systematic cycle takes p lace in the left region of the heart while the chasten side handles the pulmonary cycle. The mitral valve at the upper part of the left-side chamber is pressed open by blood and allows it to trickle down to the left ventricle (Sherwood, 2012). The blood is then pumped directly into the aorta and is rich in oxygen. It is then transported to all other parts of the body and organs. Used blood is then collected back to the heart through two main veins. One is the inferior nervure cava, which takes blood to the heart from the lower body sections. The other is the superior vena cava, which collects blood from the upper body. These two drain the blood into the upper right chamber (Solomon, Berg and Martin, 2010). Blood, from there, picks up the pulmonary cycle and gets to the right lower chamber from the right upper chamber. The blood is forced into the pulmonary artery which is divided into two one part into the right and the other to the left lungs. The pulmonary veins carry the rich o xygen blood back to the left atrium, and the cycle continues.
