What is blood pressure defined as?

Blood pressure is defined as the amount of force exerted against the walls of an artery by the blood. This definition is crucial because it captures the dynamic relationship between the heart's function and the vascular system. When the heart beats, it pumps blood into the arteries, creating a force that can be measured. This force is essential for understanding cardiovascular health, as it contributes to the overall blood circulation throughout the body.

Elevated or decreased blood pressure can indicate various health issues, such as hypertension or hypotension, making it a critical parameter in monitoring a patient's health. Understanding blood pressure in this context assists healthcare providers in diagnosing and managing conditions related to the cardiovascular system.
