In the case of atherosclerosis (which often occurs in the elderly), the vessel walls are less elastic, making it difficult for blood to move. The resistance of the artery walls to the blood will increase, causing the blood pressure to rise.

Blood volume: Low blood volume will lead to low blood pressure because there is not enough blood to put pressure on the artery walls.

This condition occurs when each person loses too much blood, and blood pressure will drops, which is life-threatening when there is not enough blood to carry around the body.
