It is also the mean arterial pressure that is carefully regulated by short-term and long-term regulatory and compensatory mechanisms. The mean arterial pressure is a time-weighted average of pressure values in large systemic arteries during the cardiac cycle.
The blood pressure in the large artery of the heart, the aorta, and the other large arteries of a healthy adult is usually 120 mm Hg during the contraction of the heart (systole), and 80 mm Hg during relaxation of the heart (diastole). For adults, a normal reading can be anywhere from 120/70 to 140/90.
