The Heart Anatomy And Physiology

Your center has 4 chambers. The upper chambers are called the leave and dependable atria, and the lower chambers are called the go forth and right-hand(a) ventricles. A wall of muscle called the septum separates the leftover(a) and right atria and the left and right ventricles. The left ventricle is the largest and unbendableest chamber in your heart. The left ventricles chamber walls are only about a half-inch thick, just they have enough promote to push blood by means of the aortic valve and into your body. (British Heart Foundation 2010)
The Physiology of the System
The heart is the muscular organ of the circulatory system that constantly pumps blood throughout the body. The heart is composed of cardiac muscle tissue that is very 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 coming 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 condensation of the cardiac muscle tissue in the ventricles is called systole. When the ventricles contract they force 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
