each have three semi-lunar cusps‚ which curve outward and into the opening of the receiving blood vessel. What separates the semilunar valves from the atrioventricular (AV) valves is that the semilunar valves contain no presence of papillary muscles or chordae tendineae. This is because pressure within the heart falls in this area‚ thereby forcing the semilunar valves to close on their own. The hearts is a prime member of the circulatory system: the system that circulates blood and lymph through the

Mitral Valve Prolapse Human Anatomy and Physiology II Kristen Ammen The mitral valve is located on the left side of the heart between the left atrium and left ventricle. The purpose of the mitral valve is to form a seal between these two chambers of the heart to prevent the back flow of blood. When blood enters the left side of the heart‚ it is oxygenated and enters through the pulmonary veins. The blood then travels through the left atrium; the bicuspid (mitral) valve then opens to let the

Aortic valve stenosis occurs in approximately 5 out of every 10‚000 people.1 It occurs more commonly
