The pulse pressure of human :-

Options

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

Answer

To solve the question regarding the pulse pressure of humans, we need to understand the concept of blood pressure and how to calculate pulse pressure.

### Step-by-Step Solution:

1. **Understand Blood Pressure**: Blood pressure is typically expressed as two numbers, for example, 120/80 mmHg. The first number (systolic pressure) is the pressure in the arteries when the heart beats, and the second number (diastolic pressure) is the pressure in the arteries when the heart is at rest between beats.

2. **Identify the Values**: In the example given, the systolic pressure is 120 mmHg and the diastolic pressure is 80 mmHg.

3. **Calculate Pulse Pressure**: Pulse pressure is calculated by subtracting the diastolic pressure from the systolic pressure.
\[ \text{Pulse Pressure} = \text{Systolic Pressure} - \text{Diastolic Pressure} \]
Using the values from our example:
\[ \text{Pulse Pressure} = 120 \, \text{mmHg} - 80 \, \text{mmHg} = 40 \, \text{mmHg} \]

4. **Conclusion**: Therefore, the pulse pressure of humans is 40 mmHg.

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