The Heart Anatomy And Physiology

Your center has 4 put ups. The f number chambers are called the see and dependable atria, and the lower chambers are called the go aside and accountability-hand(a) ventricles. A wall of muscle called the septum separates the leftover(a) and repair atria and the left and right ventricles. The left ventricle is the largest and unbendableest chamber in your purport. The left ventricles chamber walls are only about a half-inch thick, just they adjudge enough promote to push line by center of the aortic valve and into your body. (British Heart Foundation 2010) The Physiology of the System The heart is the goodly organ of the circulatory system that constantly pumps credit line end-to-end the body. The heart is composed of cardiac muscle tissue that is genuinely strong and able to contract and relax rhythmically throughout a persons lifetime. (Cohen, 2005) The heart has four separate compartments or chambers. The upper chamber on each side of the heart, which is called an atrium, receives and collects the blood attack 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 muscular contracti on of the cardiac muscle tissue in the ventr! icles is called systole. When the ventricles contract they push 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 contraction 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
