The heart has three layers. They are the: Epicardium: This thin membrane is the outer-most layer of the heart. Myocardium: This thick layer is the muscle that contracts to pump and propel blood ...
Cross-section. The chambers of the heart operate as a ‘double-pump’ system for the body’s circulation. In coordination with valves, the chambers work to keep blood flowing in the proper ...
The heart is a muscular organ situated in the mediastinum.It consists of four chambers, four valves, two main arteries (the coronary arteries), and the conduction system. The left and right sides of the heart have different functions: the right side receives de-oxygenated blood through the superior and inferior venae cavae and pumps blood to the lungs through the pulmonary artery, and the left ...
The circulatory system works thanks to constant pressure from the heart and valves throughout the body. This pressure ensures that veins carry blood to the heart and arteries transport it away ...
Cardiac physiology. Cardiac physiology or heart function is the study of healthy, unimpaired function of the heart: involving blood flow; myocardium structure; the electrical conduction system of the heart; the cardiac cycle and cardiac output and how these interact and depend on one another.
The left ventricle is one of four chambers of the heart. It is located in the bottom left portion of the heart below the left atrium, separated by the mitral valve. As the heart contracts, blood ...
Coronary arteries function primarily to bring blood to your heart muscle. Without keeping the heart muscle oxygenated, you would be at greater risk of heart disease and heart attacks. Most people ...
Organs. The chest is the area of origin for many of the body’s systems as it houses organs such as the heart, esophagus, trachea, lungs, and thoracic diaphragm. The circulatory system does most ...
