   Aug 31, 2023 · The leaflets and cusps that make up the heart valves are made up of layers of connective tissue that are histologically divided into three layers. The semilunar valves are divided into: Ventricularis - which is in direct contact with pulsatile blood and directed toward the ventricles. It is the most caudal layer.

   Dec 22, 2017 · The valves of the heart are structures which ensure blood flows in only one direction. They are composed of connective tissue and endocardium (the inner layer of the heart). There are four valves of the heart, which are divided into two categories: Atrioventricular valves: The tricuspid valve and mitral (bicuspid) valve. They are located ...

   Mar 24, 2022 · The heart is made of three layers of tissue. Endocardium is the thin inner lining of the heart chambers and also forms the surface of the valves. Myocardium is the thick middle layer of muscle that allows your heart chambers to contract and relax to pump blood to your body. Pericardium is the sac that surrounds your heart. Made of thin layers ...

   Oct 30, 2023 · The mitral valve is located on the left side of the heart, while the tricuspid valve is found on the right side. The outlet valves allow blood to leave the heart to one of two destinations. From the right side of the heart, blood leaves the right ventricle and passes through the pulmonary valve to gain access to the lungs via the pulmonary arteries .

   • 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!)

   The heart is composed of three layers: the epicardium (outer layer) which prevents excess expansion or movement of the heart, the myocardium (middle layer) which initiates contractions driving the cardiac cycle, and the endocardium (inner layer) that lines the cavities and valves. The heart contains two upper chambers called atria and two lower ...

   What are the 3 layers of the heart?

   • The heart contains three basic layers similar to those seen in arteries and veins. The outermost layer is the epicardium, which is derived from the proepicardium (from the septum transversum). The middle layer is the myocardium, and the innermost layer is the endocardium, which originated from mesothelial cells of the outflow tract.

    The left ventricle is the major pumping chamber for the systemic circuit; it ejects blood into the aorta through the aortic semilunar valve. Heart Valve Structure and Function. A transverse section through the heart slightly above the level of the atrioventricular septum reveals all four heart valves along the same plane (Figure 6.1.11).
