The force of blood against the walls of blood vessels is known as blood pressure. It is a measure of the pressure exerted by circulating blood on the walls of the blood vessels, and it is typically expressed in millimeters of mercury (mmHg). Blood pressure is commonly represented as two numbers: systolic pressure (the pressure when the heart beats) over diastolic pressure (the pressure when the heart is at rest between beats). For example, a normal blood pressure reading might be 120/80 mmHg.
Blood pressure is influenced by several factors, including the strength and rate of the heart's contractions, the volume of blood, the resistance of the blood vessels, and the overall elastic properties of the vascular system. Maintaining healthy blood pressure levels is important for overall cardiovascular health.
