An adult human with average health has systolic and diastolic pressures as

Options

A. 120 mm Hg and 80 mm Hg
B. 50 mm Hg and 80 mm Hg
C. 80 mm Hg and 80 mm Hg
D. 70 mm Hg and 120 mm Hg

Answer

To solve the question regarding the systolic and diastolic pressures of an adult human with average health, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Blood Pressure**: Blood pressure is measured in two values: systolic and diastolic. Systolic pressure is the pressure in the arteries when the heart beats, while diastolic pressure is the pressure in the arteries when the heart is resting between beats.

2. **Identifying Normal Values**: For an adult human with average health, the normal systolic blood pressure is typically around 120 mmHg, and the normal diastolic blood pressure is around 80 mmHg.

3. **Analyzing the Given Options**: The options provided are:
- 120 mmHg and 80 mmHg
- 50 mmHg and 80 mmHg
- 80 mmHg and 80 mmHg
- 70 mmHg and 120 mmHg

4. **Selecting the Correct Answer**: Among the options, the first one (120 mmHg and 80 mmHg) matches the normal values for an adult human with average health.

5. **Conclusion**: Therefore, the correct systolic and diastolic pressures for an adult human with average health are **120 mmHg and 80 mmHg**.

### Final Answer:
**120 mmHg and 80 mmHg**
