MEDICAL PHYSIOLOGY

Detailed explanation-1: -Blood pressure is the force of the blood pushing against the artery walls. The force is generated with each heartbeat as blood is pumped from the heart into the blood vessels. The size and elasticity of the artery walls also affect blood pressure.

Detailed explanation-2: -Due to contraction of the heart, pressure is exerted on the walls of the arteries known as blood pressure.

Detailed explanation-3: -Blood Pressure = force per unit area exerted on vessel wall. Expressed in mmHg.

Detailed explanation-4: -The force per unit area is the blood pressure and it is measured by using a device called a sphygmomanometer, which reads the pressure during systole (contraction of the ventricle) and diastole (relaxation of the ventricle) at the aorta. Blood pressure varies within the different types of blood vessels.
