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 answer the question "Which of the following organ systems jointly coordinate and integrate all the activities of the body organs?", we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Organ Systems Involved**: The question refers to organ systems that are responsible for coordination and integration of body activities. The primary systems to consider are the nervous system and the endocrine system.

2. **Understand the Role of the Nervous System**: The nervous system is responsible for rapid communication between different parts of the body. It uses electrical signals to transmit information quickly, allowing for immediate responses to stimuli.

3. **Understand the Role of the Endocrine System**: The endocrine system regulates body functions through hormones, which are chemical messengers released into the bloodstream. This system works more slowly than the nervous system but has a longer-lasting effect on the body.

4. **Evaluate Other Systems**:
- **Sensory System**: This is part of the nervous system and does not independently coordinate body functions.
- **Digestive System**: Primarily involved in processing food and does not coordinate body activities.
- **Respiratory System**: Involved in gas exchange but does not play a direct role in overall body coordination.
- **Circulatory System**: While it transports hormones, it does not coordinate activities by itself.

5. **Conclusion**: The nervous system and the endocrine system work together to coordinate and integrate all activities of the body organs. Therefore, the correct answer is that both the nervous system and the endocrine system jointly coordinate and integrate body functions.

### Final Answer:
The organ systems that jointly coordinate and integrate all the activities of the body organs are the **Nervous System and Endocrine System**.
