BP of a normal adult is

Options

A. 130/20
B. 120/80
C. 140/20
D. 120/40

Answer

To determine the blood pressure (BP) of a normal adult, we can follow these steps:

### Step-by-Step Solution:

1. **Understand Blood Pressure**: Blood pressure is defined as the force exerted by circulating blood on the walls of blood vessels. It is an important indicator of cardiovascular health.

2. **Measurement Instrument**: Blood pressure is measured using an instrument called a sphygmomanometer. This device helps in determining the pressure exerted by blood in the arteries.

3. **Normal Blood Pressure Values**: The normal blood pressure for a healthy adult is typically around 120/80 mmHg. This is expressed in millimeters of mercury (mmHg).

4. **Components of Blood Pressure**:
- **Systolic Pressure**: The first number (120) represents the systolic pressure, which is the pressure in the arteries when the heart beats and pumps blood.
- **Diastolic Pressure**: The second number (80) represents the diastolic pressure, which is the pressure in the arteries when the heart is at rest between beats.

5. **Conclusion**: Based on the standard values, the normal blood pressure for an adult is 120/80 mmHg. Therefore, if given options, the correct answer would be the one that states this value.

### Final Answer:
The blood pressure of a normal adult is **120/80 mmHg**.
