In human heart, maximum pressure in normal functioning heart will develop during systole at :-

Options

A. Right atrium
B. Left atrium
C. Right ventricle
D. Left ventricle

Answer

To determine where the maximum pressure in a normal functioning human heart develops during systole, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Heart Chambers**: The human heart consists of four chambers: the right atrium, right ventricle, left atrium, and left ventricle. Each chamber has a specific function in the circulation of blood.

2. **Define Systole**: Systole refers to the phase of the heartbeat when the heart muscle contracts and pumps blood out of the chambers. Maximum pressure in the heart occurs during this phase.

3. **Analyze Each Chamber**:
- **Right Atrium**: This chamber receives deoxygenated blood from the body. During systole, it does not generate maximum pressure because it is primarily filling with blood.
- **Left Atrium**: This chamber receives oxygenated blood from the lungs. Similar to the right atrium, it does not generate maximum pressure during systole.
- **Right Ventricle**: This chamber pumps deoxygenated blood to the lungs for oxygenation. While it does generate pressure, it is not the highest pressure in the heart.
- **Left Ventricle**: This chamber pumps oxygenated blood to the rest of the body. During systole, it generates the highest pressure because it has to overcome the systemic vascular resistance to deliver blood effectively.

4. **Conclusion**: The left ventricle develops the maximum pressure during systole in a normal functioning heart.

### Final Answer:
The maximum pressure in a normal functioning heart develops during systole at the **left ventricle**.
