Define pulse and Blood pressure.

Pulse:
A pulse refers to the rhythmic expansion and contraction of the arteries, which occurs in response to the pumping action of the heart. It is typically measured as the palpable throbbing or pulsation felt in an artery, most commonly the radial artery in the wrist or the carotid artery in the neck. The pulse is a vital sign used in medical assessments to evaluate a person's heart rate, rhythm, and overall cardiovascular health. It is usually expressed in beats per minute (BPM) and can vary based on factors such as age, physical activity, and medical conditions. A normal resting pulse rate for adults is typically between 60 and 100 beats per minute.

Blood Pressure:
Blood pressure refers to the force of blood exerted against the walls of arteries as the heart pumps it through the circulatory system. It is measured in millimeters of mercury (mm Hg) and is typically expressed as two values:

Systolic Pressure: The higher of the two numbers, representing the pressure in the arteries when the heart contracts (systole) and pushes blood into the circulation.

Diastolic Pressure: The lower number, representing the pressure in the arteries when the heart is at rest between beats (diastole).

For example, a typical blood pressure reading might be expressed as "120/80 mm Hg," where 120 is the systolic pressure, and 80 is the diastolic pressure.

Blood pressure is an essential indicator of cardiovascular health and is used to assess the risk of heart disease, stroke, and other circulatory problems. Normal blood pressure is usually considered to be around 120/80 mm Hg, but optimal levels can vary depending on an individual's age, health, and other factors. Abnormally high blood pressure (hypertension) or low blood pressure (hypotension) can both have adverse health effects and may require medical attention and treatment.
