Blood Pressure

Blood Pressure is the pressure of circulating blood on the walls of blood vessels.

Systolic pressure (Maximum during one heartbeat)

Diastolic Pressure (Minimum in between two heartbeats)

It is measured in millimeters of mercury (mmHg)

Blood Pressure is influenced by cardiac output, total peripheral resistance, and arterial stiffness and varies on the situation like emotional state, activity and relative health states.

Blood Pressure is regulated by baroceptors which act via the brain to influence the nervous and endocrine system.

Hypotension (Low Blood Pressure)

Hypertension (High Blood Pressure)
