   Figure 17.2.1 17.2. 1 shows the position of the heart within the thoracic cavity. Within the mediastinum, the heart is separated from the other mediastinal structures and is held in place by a tough wrapping known as the pericardium, or pericardial sac. The sac also limits the range of motion of the heart as it beats.

   Nov 3, 2023 · The endocardium has two layers. The inner layer lines the heart chambers and is made of endothelial cells. Superiorly, is the second layer: a subendocardial connective tissue which is continuous with the connective tissue of the myocardium. Branches of the heart’s conduction system are immersed into the subendocardial layer.

   • 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!)

   Which part of the heart is connected to the myocardium?

   • The innermost layer of the heart wall, the endocardium, is joined to the myocardium with a thin layer of areolar connective tissue. The endocardium lines the chambers where the blood circulates and covers the heart valves.

   What parts of the heart separate the chambers?

   • The septa are the partitions that separate the chambers of the heart. They include the interatrial septum, the interventricular septum, and the atrioventricular septum. Two of these openings are guarded by the atrioventricular valves, the right tricuspid valve and the left mitral valve, which prevent the backflow of blood.
