   May 14, 2022 · Heart valves are parts of your heart that act like doors. They open and close to let blood flow from one area of your heart to another. They help ensure that blood moves at the right time and in the correct direction. As the valves open and close, they create two sounds, which are your heartbeat.

   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.

   • 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!)
