Blood pressure regulation is an essential physiological process that ensures the maintenance of an appropriate blood flow to vital organs throughout the body. Blood pressure refers to the force exerted by circulating blood on the walls of blood vessels, particularly the arteries. This force is determined by two factors: cardiac output, which is the amount of blood the heart pumps per minute, and systemic vascular resistance, which is the resistance to blood flow offered by the blood vessels. The body has sophisticated mechanisms in place to maintain blood pressure within a narrow range, as deviations from this range can lead to serious health conditions such as hypertension or hypotension.
