In the artery,

Options

A. systolic blood pressure is lesser than diastolic blood pressure
B. the duration of systolic blood pressure is greater than the duration of diastolic blood pressure
C. the duration of systolic blood pressure is lesser than the duration of diastolic blood pressure
D. the duration of systolic blood pressure is same as the duration of diastolic blood pressure

Answer

To solve the question regarding the relationship between systolic and diastolic blood pressure in arteries, we need to understand the definitions and characteristics of both types of blood pressure.

### Step-by-Step Solution:

1. **Define Systolic Blood Pressure (SBP)**:
- Systolic blood pressure is the pressure in the arteries when the heart beats (during contraction). This is when the heart pumps blood into the arteries, causing the pressure to rise.

**Hint**: Remember that SBP occurs during heart contraction.

2. **Define Diastolic Blood Pressure (DBP)**:
- Diastolic blood pressure is the pressure in the arteries when the heart is at rest between beats (during relaxation). This is when the heart fills with blood, and the pressure in the arteries falls.

**Hint**: DBP occurs when the heart is relaxed and filling with blood.

3. **Compare the Two Pressures**:
- It is important to note that systolic blood pressure is always higher than diastolic blood pressure. This is because during systole (heart contraction), the pressure in the arteries increases significantly to push blood out.

**Hint**: SBP > DBP.

4. **Duration of Systolic vs. Diastolic Pressure**:
- The duration of systolic blood pressure is shorter than that of diastolic blood pressure. This is because the heart spends more time in diastole (relaxation) than in systole (contraction) during the cardiac cycle.

**Hint**: The heart spends more time relaxing than contracting.

5. **Conclusion**:
- Based on the definitions and comparisons, the correct statement is that the duration of systolic blood pressure is lesser than the duration of diastolic blood pressure.

### Final Answer:
The correct answer is that the duration of the systolic blood pressure is lesser than the duration of the diastolic blood pressure.
