- The heart consists of several layers of a tough muscular wall, the myocardium. A thin layer of tissue, the pericardium, covers the outside, and another layer, the endocardium, lines the inside. The heart cavity is divided down the middle into a right and a left heart, which in turn are subdivided into two chambers.
1. The two atria hold the blood that circulates away from the heart. 2. The heart has four chambers and is divided into a right and left side by a muscular wall called the septum. 3. The heart is located inside the ribcage and just to the right of the breast bonde. 4. The average heart beats about 100,000 times a day.

Nov 3, 2023 · This article will discuss the layers of the heart (the epicardium, the myocardium and the endocardium) and any clinical relations pertaining to them. In the same way that vehicles have their fuel pumps, our body has the heart. The heart is a muscular organ found in the middle mediastinum that pumps blood throughout the body.
- Heart anatomy. The heart has five surfaces: base (posterior), diaphragmatic (inferior), sternocostal (anterior), and left and right pulmonary surfaces. It also has several margins: right, left, superior, and inferior
- Heart valves. Heart valves separate atria from ventricles, and ventricles from great vessels. The valves incorporate two or three leaflets (cusps) around the atrioventricular orifices and the roots of great vessels.
- Blood flow through the heart. The blood flow through the heart is quite logical. It happens with the heart cycle, which consists of the periodical contraction and relaxation of the atrial and ventricular myocardium (heart muscle tissue).
- Coronary circulation. The heart must also be supplied with oxygenated blood. This is done by the two coronary arteries: left and right. Heart muscles work constantly (thank goodness!)
Oct 30, 2023 · Test your ability to correctly identify structures. Challenge your ability to connect anatomy with clinical practice. Let you see a structure from multiple perspectives, for extra clarity. You can start learning the anatomy of the heart with the following quiz.
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 side receives saturated blood from the lungs.
