The pulse pressure of human :-

Options

A. 80 mmHg
B. 40 mmHg
C. 120 mmHg
D. 70 mmHg

Answer

### Step-by-Step Solution:

1. **Understanding Pulse Pressure**:
- Pulse pressure is defined as the difference between systolic pressure and diastolic pressure.
- Systolic pressure is the pressure in the arteries during the contraction of the heart, while diastolic pressure is the pressure in the arteries when the heart is at rest between beats.

2. **Identifying Systolic and Diastolic Pressures**:
- The typical systolic pressure in a healthy human is approximately 120 mmHg.
- The typical diastolic pressure in a healthy human is approximately 80 mmHg.

3. **Calculating Pulse Pressure**:
- To find the pulse pressure, subtract the diastolic pressure from the systolic pressure:
\[ \text{Pulse Pressure} = \text{Systolic Pressure} - \text{Diastolic Pressure} \]
- Plugging in the values:
\[ \text{Pulse Pressure} = 120 \, \text{mmHg} - 80 \, \text{mmHg} = 40 \, \text{mmHg} \]

4. **Conclusion**:
- The pulse pressure of a human is therefore 40 mmHg.

### Final Answer:
The pulse pressure of a human is **40 mmHg**.
