How do you write an expository paragraph about blood pressure?

Blood pressure is the force exerted by the blood against the walls of blood vessels, and it is essential for maintaining proper circulation. Blood pressure is measured in millimeters of mercury (mm Hg) and is typically expressed as two numbers—systolic blood pressure and diastolic blood pressure. Systolic blood pressure is the pressure in the arteries when the heart beats, while diastolic blood pressure is the pressure in the arteries between heartbeats. Hypertension, or high blood pressure, is defined as a blood pressure reading of 140/90 mm Hg or higher. Hypertension can lead to several severe health problems, including heart disease, stroke, kidney failure, and vision loss. Regular monitoring, lifestyle modifications such as a balanced diet, regular exercise, stress management, and medication if needed, are essential in managing blood pressure and preventing its long-term complications.
