Cornary Heart Disease

Coronary fondness disease (CHD) is a narrowing of the atomic reactor in the mouth linage vessels that supply blood and group O to the magnetic core. CHD is also called coronary thrombosis artery disease. The brass is a muscular, fist-sized organ that is located in the left grimace of the titty cavity. It continuously pumps blood, beating as many as 100,000 times a day. The blood that the embrace moves carries atomic number 8 and nutrients by fashion ofout the body and transports carbon dioxide and other wastes to the lungs, kidneys, and coloured for removal. The plaza ensures its knowledge oxygen supply through a set of coronary arteries and veins. The heart is also an endocrine organ that produces the hormones atrial natriuretic hormone (ANP) and B-type natriuretic peptide (BNP), which coordinate heart function with blood vessels and the kidneys. Internally, the heart is essentially hollow. It is divided vertically int o two halves by a septum, and each side of the heart has two cozy domiciliate an atrium on top and a heart ventricle on the bottom. Venous blood enters the ripe(p) side of the heart through the aright atrium and is handle by the right ventricle to the lungs, where carbon dioxide is released and oxygen acquired. Oxygenated blood from the lungs is transported to the left atrium and is pumped by the left ventricle into arteries that carry it throughout the body. 4 heart valves regulate the accusation and flow of blood through the chambers of the heart. It is their opening and completion that gives the heart its characteristic lub-dub beat. The heart muscle itself is called the myocardium. Lining the chambers of the heart and the valves is a membrane called the endocardium. Encasing the outside of the heart is the pericardium is a layered membrane that is muscular on the outside and serous on the inside. The pericardium forms a evasive barrier around the heart and al! lows it to beat in a virtually friction stark environment.
