Question

How do systolic and diastolic blood pressure values relate to the action of the heart and movement of blood in arteries? quizley

Answer 1

Answer:

ventricles contract and movement of blood is towards the body in systolic blood pressure and ventricles relax and movement of blood is towards heart in distolic blood pressure.

Explanation:

Blood pressure is the pressure exerted by blood on the walls of blood vessels. The standard blood pressure in human adults is 120/80.

During Systolic blood pressure, the heart ventricles contract and pump the blood to arteries, arterioles, capilaries then venules and veins from an area of higher pressure to lower pressure. Simply, the heart pumps the oxygenated blood towards the body. It is the higher value (120).

The Diastolic blood pressure is lower arterial pressure (80) and produced during ventricular relaxation. During diastolic blood pressure, the heart refills it and thus deoxygenated blood move towards heart from body.
