What is an endocardium?
endocardium is the innermost layer of heart tissue that lines the cavities and valves of the heart. This layer is composed of free connective tissue and simple spinocellular epithelial tissue. The endocardium regulates heart contraction, helps heart development and can regulate the composition of blood that feeds the heart tissues. The hard, outer fibrous layer of parietal pericardium protects the heart and root on site. The thin, inner serous layer connects the bag with a heart that consists of three layers. On the outside, the epicardium, also called visceral pericardium, consists of connective tissue and fat. The visceral pericardium is freely connected with a parietal pericardium and firmly with myocardium, the middle layer of tissue in the heart. Myocardium is responsible for heart contractions that occur spontaneously or without stimulation from the nervous system. These contractions allow blood to enter the hall and pumping blood from the chambers. The endocardium is an inner layer of heart that connects with myocardium and lines the atrial and chamber.
People have four chambers in their hearts: the right chamber and the left chamber in the lower two quadrants of the heart and the right hall and the left atrium in the upper two quadrants of the heart. The atrie receives blood from the body and passes it to the body through atrioventricular (AV) valves. The chambers receive blood from atrials and pump it into the body.
Blood, which has already been circulated and "used" by the body, is pumped to the right atrium, which then passes it to the right chamber. The right chamber receives de-oxyenatted blood from the right atrium and pumps blood into the lungs to pick up more oxygen. The left atrium takes back ooxygenated blood and goes to the left ventricle, which in turn pumps the blood into the body. The muscle in the myocardium performs contractions that move through the heart, control the valves between the chambers and pump blood from the heart. The endocardium does not start these contractions, but helps to regulate them.
endocardium limits the walls of atrial and chambers and the valves between them. Endocardial cell makeup is a close layer of endothelium, tissueThe layers that line the inside of the blood vessels. On its luminous side or on the side closest to the cavities of the heart consists of a simple spinocellular epithelium, one layer of scaly cells. Below it lies a layer of free connective tissue, tissue with variable, widely distributed fibers.
usually leads the heart injury of heart attacks do not expand only in inside as an endocardium, but if so, it can be very serious. Damage to the inner lining of the heart can negatively affect the heart's ability to download at a quick and regular pace. Diseases such as endocarditis, endocardial bacterial infections are more typical in people with damaged cardiac valves.
