Which of the following organ systems jointly coordinate and integrate all the activities of the body organs ?

Options

A. Neural system and sensory system
B. Digestive system and respiratory system
C. Neural system and endocrine system
D. Circulatory systme and respiratory system

Answer

To solve the question "Which of the following organ systems jointly coordinate and integrate all the activities of the body organs?", we will analyze the options provided and determine which systems work together for coordination and integration.

### Step-by-Step Solution:

1. **Understanding the Options**:
The options given are:
- Neural system
- Sensory system
- Digestive system and respiratory system
- Neural and endocrine system
- Circulatory system and respiratory system

2. **Analyzing Each Option**:
- **Digestive and Respiratory System**: These systems work together to provide energy to the body. The digestive system breaks down food, while the respiratory system provides oxygen. However, they do not coordinate and integrate all body activities.

- **Neural and Endocrine System**: The nervous system receives information from the environment and generates responses. The endocrine system releases hormones that regulate various bodily functions, including growth, metabolism, and reproduction. Together, they coordinate and integrate the activities of all body organs effectively.

- **Sensory System**: This system detects stimuli and sends signals to the central nervous system. While it plays a role in coordination, it does not act alone in integrating all body activities.

- **Circulatory and Respiratory System**: These systems work together to supply oxygen and remove carbon dioxide. While they are essential for sustaining life, they do not coordinate all body activities.

3. **Conclusion**:
After analyzing the options, the correct answer is **Neural and Endocrine System**. These two systems work together to coordinate and integrate the activities of all body organs.

### Final Answer:
**Neural and Endocrine System**
