Difference between systolic and diastolic blood pressure is

Options

A. 120 mm Hg
B. 80 mm Hg
C. 40 mm Hg
D. 200 mm Hg

Answer

To find the difference between systolic and diastolic blood pressure, we can follow these steps:

1. **Understand the Definitions**:
- Systolic pressure is the pressure in the blood vessels when the heart beats and pumps blood. It is typically around 120 mm Hg.
- Diastolic pressure is the pressure in the blood vessels when the heart is at rest between beats. It is usually around 80 mm Hg.

2. **Identify the Values**:
- Systolic pressure = 120 mm Hg
- Diastolic pressure = 80 mm Hg

3. **Calculate the Difference**:
- To find the difference between systolic and diastolic pressure, subtract the diastolic pressure from the systolic pressure:
\[ \text{Difference} = \text{Systolic Pressure} - \text{Diastolic Pressure} \]
\[ \text{Difference} = 120 \, \text{mm Hg} - 80 \, \text{mm Hg} = 40 \, \text{mm Hg} \]

4. **Conclusion**:
- The difference between systolic and diastolic blood pressure is 40 mm Hg.

**Final Answer**: 40 mm Hg
