In emergency condition, all changes occur in our body except

Options

A. Heart beat increases
B. Dilates blood vessels of brain, lungs, heart and striated muscle
C. Brochodilation
D. Micturition is done

Answer

To answer the question "In emergency condition, all changes occur in our body except," we need to analyze the options provided and determine which one does not occur during an emergency situation.

### Step-by-Step Solution:

1. **Understanding Emergency Conditions**:
- In emergency situations, the body undergoes several physiological changes to prepare for a "fight or flight" response. This includes the release of stress hormones like epinephrine (adrenaline) and norepinephrine.

2. **Analyzing the First Option - Heartbeat Increases**:
- During emergencies, the heart rate increases due to the release of epinephrine and norepinephrine. This helps pump more blood to vital organs and muscles.
- **Conclusion**: This option is incorrect because the heartbeat does increase in emergencies.

3. **Analyzing the Second Option - Dilation of Blood Vessels**:
- In an emergency, blood vessels in the brain, lungs, heart, and striated muscles dilate to increase blood flow to these areas. This is part of the body's response to stress.
- **Conclusion**: This option is also incorrect as blood vessel dilation occurs during emergencies.

4. **Analyzing the Third Option - Bronchodilation**:
- Bronchodilation refers to the widening of the bronchi and bronchioles in the lungs, which increases airflow and respiratory rate. This is also a response to emergency conditions, allowing for more oxygen intake.
- **Conclusion**: This option is incorrect because bronchodilation does occur during emergencies.

5. **Identifying the Correct Answer**:
- Since all the options provided indicate changes that occur during an emergency condition, we need to identify which change does not happen. However, based on the analysis, it appears that all options listed are indeed changes that occur during emergencies.

6. **Final Conclusion**:
- If the question is asking for a change that does not occur, it may be a trick question or there may be an error in the options provided. All listed changes (increased heartbeat, dilation of blood vessels, and bronchodilation) are physiological responses to emergencies.
