Q
Definition of Blood pressure (BP)
A
hydrostatic pressure of the blood in the blood vessels from the contraction of the ventricles moving blood away from the heart. Blood pressure drops naturally as we move away from the heart,and is lowest in the systemic venules and veins. Blood Pressure is also dependent upon blood volume, if blood volume decreases then blood pressure decreases vice versa!
