Blood pressure that is too low is called hypotension, pressure that is consistently too high is called hypertension, and normal pressure is called normotension.
What is normal blood pressure regulation?
Systolic blood pressure measures the amount of pressure that blood exerts on vessels while the heart is beating. The optimal systolic blood pressure is 120 mmHg. Diastolic blood pressure measures the pressure in the vessels between heartbeats. The optimal diastolic blood pressure is 80 mmHg.
How does blood pressure get regulated?
The force is generated by each heartbeat as blood is pumped from the heart into the blood vessels. The size, tone and elasticity of the arteries walls also affect blood pressure. The kidneys regulate blood pressure as well by regulating the amount of fluid and salt in the body.

What is the dictionary definition of blood pressure?

How is blood pressure regulated in the body?
the pressure exerted by the circulating volume of blood on the walls of the arteries and veins and on the chambers of the heart. Blood pressure is regulated by the homeostatic mechanisms of the body by the volume of the blood, the lumen of the arteries and arterioles, and the force of cardiac contraction.
How is blood pressure controlled in non mammals?
Blood pressure regulation involves the renin-angiotensin system in non-mammals similar to that of mammals and natriuretic peptides antagonize Ang-II actions. Blood pressure regulation depends very significantly on the modulation of aldosterone concentration by an integrated system of checks and balances.
