MEDICAL PHYSIOLOGY

Detailed explanation-1: -Systolic pressure is the maximum blood pressure during contraction of the ventricles; diastolic pressure is the minimum pressure recorded just prior to the next contraction. The blood pressure is usually written as the systolic pressure over the diastolic pressure (e.g., 120/80 mm Hg).

Detailed explanation-2: -Systole is when the heart muscle contracts. When the heart contracts, it pushes the blood out of the heart and into the large blood vessels of the circulatory system. From here, the blood goes to all of the organs and tissues of the body. During systole, a person’s blood pressure increases.

Detailed explanation-3: -Blood pressure is recorded as two numbers, the systolic pressure (the pressure when the heart beats) over the diastolic pressure (the pressure when the heart relaxes between beats). We record this with the systolic pressure first (on the top) and the diastolic pressure second (below).
