the heart is a fist sized muscle located in the chest cavity to the left of the midline. And it is composed of three major components layers, chambers and valves. The three layers are the endo cardi. Um The inner layer of the chambers and valves. Epic RD um the outer layer and myocardial. Um the middle layer composing the actual heart muscle. There are two types of chambers in the heart, the left and right atria that formed the two upper chambers receiving blood into the heart and the right and left ventricles that form the two lower chambers, pumping blood out of the heart. These four chambers are separated by two septa or membranes. The inter atrial septum dividing the two atria and the inter ventricular septum dividing the two ventricles. Four valves ensure the correct direction and amount of blood flow in the heart mitral valve, pulmonary semi lunar valve aortic, semi lunar valve and tried cusp valve. These three heart components layers, chambers and valves work with veins and arteries to move blood throughout the body veins carry blood back to the heart via the superior and inferior vena cave arteries carry the blood through the lungs for oxygenation and then back to the heart for subsequent distribution to the body. The entire cardiac cycle is controlled by the heart's natural pacemaker, the sino atrial node. The rhythmic pulsations conduct through the atria ventricular node down the atrial ventricular bundle and through the perkin gee fibers, jumpstarting contraction of the ventricles some pathological conditions affecting the heart include in china, victories, bacterial endocarditis, cardiac arrhythmia, congenital heart disease. Congestive heart failure, coronary artery disease, heart murmur, hypertensive heart disease, mitral valve prolapse and rheumatic heart disease. The most common types of drugs used to correct cardiovascular conditions include angiotensin converting enzyme inhibitors, valdosta rhone antagonists, anti arrhythmic anticoagulants, antihypertensive beta blockers, calcium channel blockers and lipid lowering agents.
