the biomechanical ramifications of their function in that their mechanics are multi-modal and their loading cycle is repeated every second. For example, they must replicate this feat with each heart beat; over a period of 70 years the reader's heart valves will open and close nearly 3×109...
In this review, we discussed the complex structure of the native heart valve as well as their contributions to the valve's cyclic work. In addition, representative and state of the art studies of biomimetic heart valves inspired by the natural valve are also introduced. Based on these, the ...
Stage 1-Ventricular diastole, atrial systole- Both ventricles relax simultaneously. This results in lower pressure in each ventricle compared to each atrium above. The atrioventricular valves open partially. This is followed by the atria contracting which forces blood through the atrioventricular valves....

Heart valves (HVs) are cardiac structures whose physiological function is to ensure directed blood flow through the heart over the cardiac cycle. While primarily passive structures that are driven by forces exerted by the surrounding blood and heart, this description does not adequately describe their...

(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...
Key Structure–Function Correlations in the Cardiac Valves Heart valves are structural specializations of the cardiac tissues that ensure unidirectional blood flow through the heart; they open and close approximately 40 million times a year and three billion times over an average lifetime. Normal valve...
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 (between the right ventricle and the pulmonary artery)....
