ANATOMY

Detailed explanation-1: -The force that blood exerts force against the wall of a vessel is called blood pressure. 2. The pressure of blood inside the artery during contraction is called systolic pressure and pressure in an artery during relaxation is called diastolic pressure.

Detailed explanation-2: -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-3: -blood pressure, force originating in the pumping action of the heart, exerted by the blood against the walls of the blood vessels; the stretching of the vessels in response to this force and their subsequent contraction are important in maintaining blood flow through the vascular system.

Detailed explanation-4: -Blood pressure is measured using two numbers: 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-5: -The systolic blood pressure is defined as the maximum pressure experienced in the aorta when the heart contracts and ejects blood into the aorta from the left ventricle (approximately 120 mmHg).
