What is the function of the heart valves?Heart Valves:There are four valves in the heart: tricuspid valve (between the right atrium and right ventricle), mitral valve (between the left atrium and left ventricle), aortic valve (between the left ventricle and aorta), and pulmonary valve (betwe...
These openings are periodically shut and open by the heart valves, depending on the phase of the heart cycle. Although there are a lot of structures in the heart diagrams, you shall not worry, we’ve got them all covered for you in these articles and video tutorials. Be sure to check...

Diseased heart valves can be addressed in several ways. If repair or replacement becomes necessary, there are treatment options to consider. A team of medical specialists will be committed to your safety and comfort before, during and after your procedure. ...
(a) Where are the atrioventricular and semilunar valves of the heart located? (b) What are the functions of these valves? (c) Why are the valves important for survival? (d) How are they structurally different? Mention the four valves of the heart. What is the function of these val...
valves. In contrast,Figures 4-13and4-14show dynamic motion of the mitral valve (in long-axis and short-axis perspectives, respectively) in a 75-year-old woman with a holosystolic murmur and a diastolic rumble onphysical examination. Planimetry of the valvular annulus at peak opening can be...
This review will discuss the heart's anatomy, focusing on the chambers, great vessels, and valves. The human heart is located in the mediastinum, a cavity between the right and left lungs. It is positioned slightly to the left of the center of the chest
Heart Valves Blood flows through the heart in one direction: from the atria to the ventricles and out the great arteries leaving the superior aspect of the heart. Four valves enforce the one-way traffic. They open and close in response to differences in blood pressure. ...
