MEDICAL PHYSIOLOGY

Detailed explanation-1: -The systolic blood pressure is defined as the maximum pressure experienced in the aorta when the heart contracts and ejects blood into the aorta from the left ventricle (approximately 120 mmHg).

Detailed explanation-2: -For the right ventricle, systolic pressure is normally 25 to 30 mm Hg, with end-diastolic pressures of 5 to 7 mm Hg. The systolic pressure in the left ventricle increases with age and should equal the systolic arterial pressure. The end-diastolic pressure is typically less than 10 mm Hg.

Detailed explanation-3: -Cardiac cycle events can be divided into diastole and systole. Diastole represents ventricular filling, and systole represents ventricular contraction/ejection. Systole and diastole occur in both the right and left heart, though with very different pressures (see hemodynamics below).
