In addition, vitamin C has other very good properties, but both in apple and in the human body the antioxidant function is present, that is why it is often used in fruit salads so that the apple does not turn dark
Mitral regurgitation is a leakage of blood that flows backward via the mitral valve during contraction of the left ventricle which results in systolic murmur.
<u>Explanation:</u>
Mitral valve is seen between the left atrium and left ventricle,it prevents the back flow of blood during left ventricular contraction. In case of mitral valve regurgitation or stenosis condition it results in back flow of blood to left atrium it further results in increased blood pressure in left atrium and fluid buildup in lungs and leads to systolic murmur. During cardiac cycle systole occurs when heart contracts and diastole occurs when heart relaxes.
La magnitud del campo eléctrico se define simplemente como la fuerza por carga en la carga del ensayo. ... Dado que el campo eléctrico se define como una fuerza por carga, sus unidades serían unidades de fuerza divididas por unidades de carga. En este caso, las unidades métricas estándar son Newton/Coulomb o N/C.
