MICROANATOMY

Detailed explanation-1: -Systolic blood pressure, the top number, measures the force the heart exerts on the walls of the arteries each time it beats. Diastolic blood pressure, the bottom number, measures the force the heart exerts on the walls of the arteries in between beats.

Detailed explanation-2: -A diastolic blood pressure of somewhere between 90 and 60 is good in older folks. Once you start getting below 60, that makes people feel uncomfortable. A lot of older folks with low diastolic pressures get tired or dizzy and have frequent falls.

Detailed explanation-3: -The bottom (second) number, diastolic pressure, is always lower since it reflects the pressure inside the arteries during the resting phase between heartbeats. As it turns out, both systolic and diastolic blood pressure are important.

Detailed explanation-4: -Systolic pressure – the upper number in a blood pressure reading – measures how hard the heart pumps blood into arteries. Diastolic – the bottom number – indicates the pressure on the arteries when the heart rests between beats.
