    AI generated summary
    Blood pressure consists of two main components: systolic pressure and diastolic pressure, measured in millimeters of mercury (mmHg) or kilopascals (kPa).

    Components of Blood Pressure

    1. 1. Systolic Pressure:

    • This is the higher number in a blood pressure reading, representing the pressure in the arteries when the heart beats and pumps blood. It indicates how much pressure blood is exerting against artery walls during heart contractions. A normal systolic pressure is typically around 120 mmHg.

    1. 2. Diastolic Pressure:

    • This is the lower number in a blood pressure reading, representing the pressure in the arteries when the heart is at rest between beats. It shows how much pressure blood is exerting against artery walls while the heart is relaxed and refilling with blood. A normal diastolic pressure is usually around 80 mmHg.

    What are the components and measurement units of blood pressure?

    Blood pressure has two components:

    • Systolic pressure is the top number. It represents the pressure the heart generates when it beats to pump blood to the rest of the body.
    • Diastolic pressure is the bottom number. It refers to the pressure in the blood vessels between heartbeats.

    Blood pressure is measured in millimeters of mercury (mm Hg). So blood pressure would be expressed, for example, as 120/80 mm Hg.
