What is the definition of blood pressure?

Blood pressure is specifically defined as the force exerted by circulating blood on the walls of blood vessels, particularly arteries. This force is vital for the circulation of blood throughout the body, as it allows blood to flow to organs and tissues, delivering oxygen and nutrients while also aiding in the removal of waste products. Blood pressure is typically measured in millimeters of mercury (mmHg) and expressed as two numbers: systolic pressure, which represents the pressure during heartbeats, and diastolic pressure, which occurs when the heart is at rest between beats. Understanding this definition is crucial for recognizing its importance in cardiovascular health, as both excessively high and low blood pressure can indicate underlying health issues.
