The Heart Anatomy And Physiology

Your center has 4 chambers. The speed chambers are called the head and dependable atria, and the lower chambers are called the go frontward and cover-hand(a) ventricles. A wall of muscle called the septum separates the oddover(a) and decently atria and the left and right ventricles. The left ventricle is the largest and unbendableest chamber in your feeling. The left ventricles chamber walls are only about a half-inch thick, just they welcome enough promote to push business by heart and soul of the aortic valve and into your body. (British Heart Foundation 2010) The Physiology of the System The heart is the goodish organ of the circulatory system that constantly pumps rake passim the body. The heart is composed of cardiac muscle tissue that is in truth strong and able to contract and relax rhythmically end-to-end a persons lifetime. (Cohen, 2005) The heart has four separate compartments or chambers. The upper chamber on each side of the heart, whi ch is called an atrium, receives and collects the blood advent to the heart. The atrium past delivers blood to the powerful lower chamber, called a ventricle, which pumps blood absent from the heart through powerful, rhythmic compactions. The human heart is real two pumps in one. The right side receives oxygen-poor blood from the divers(a) regions of the body and delivers it to the lungs.

In the lungs, oxygen is absorbed in the blood. The left side of the heart receives the oxygen-rich blood from the lungs and delivers it to the rest of the body. (British Heart Foundation, 2010) The condensate of the card iac muscle tissue in the ventricles is calle! d systole. When the ventricles contract they suck the blood from their chambers into the arteries leaving the heart. The left ventricle empties into the aorta and the right ventricle into the pulmonary artery. The increased pressure due to the concretion of the ventricles is called systolic pressure. The relaxation of the cardiac muscle tissue in the ventricles is called diastole. When the ventricles relax, they make...If you want to get a full essay, order it on our website: OrderCustomPaper.com
