- The heart is a muscular organ that pumps blood throughout the body via the circulatory system. It is approximately the size of a fist and consists of four chambers: two atria and two ventricles. The heart is composed of specialized muscle tissue, known as myocardium, and is encased within a double-layered protective sac called the pericardium.

The heart is located under the rib cage -- 2/3 of it is to the left of your breastbone (sternum) -- and between your lungs and above the diaphragm.The heart is about the size of a closed fist, weighs about 10.5 ounces, and is somewhat cone-shaped. It is covered by a sack termed the pericardium or pericardialsack.The normal heart anatomy consists of a four-chambered, hollow organ.It is divided into the left and right sides by a muscular wall called the septum.Normal heart anatomy and physiology need the atria and ventricles to work sequentially, contracting and relaxing to pump blood out of the heart and then to let the chambers refill. When blood leaves each chamber of the heart, it passes through a valve that is designed to prevent the backflow of blood. There are four heart valves within the heart: 1...
