MICROANATOMY

Detailed explanation-1: -Systolic blood pressure is the pressure when the heart beats – while the heart muscle is contracting (squeezing) and pumping oxygen-rich blood into the blood vessels. Diastolic blood pressure is the pressure on the blood vessels when the heart muscle relaxes.

Detailed explanation-2: -Cardiac cycle events can be divided into diastole and systole. Diastole represents ventricular filling, and systole represents ventricular contraction/ejection.

Detailed explanation-3: -The first number, called systolic blood pressure, measures the pressure in your arteries when your heart beats. The second number, called diastolic blood pressure, measures the pressure in your arteries when your heart rests between beats.

Detailed explanation-4: -Systolic blood pressure (the first and higher number) measures pressure inside your arteries when the heart beats.

Detailed explanation-5: -Your blood pressure is highest when your heart beats, pumping the blood. This is called systolic pressure. When your heart is at rest, between beats, your blood pressure falls. This is called diastolic pressure.
