## What I do

- Study body system functions and regulation
- Analyze organ system interactions
- Investigate homeostasis mechanisms
- Research physiological adaptations
- Study exercise and environmental physiology
- Analyze physiological disorders

## When to use me

- When studying organ system function
- When analyzing homeostasis
- When investigating physiological responses
- When studying disease mechanisms
- When researching exercise physiology
- When learning integrative physiology

## Key Concepts

### Major Organ Systems

- **Cardiovascular**: Heart, blood vessels, blood
- **Respiratory**: Lungs, airways, gas exchange
- **Nervous**: Brain, spinal cord, nerves
- **Endocrine**: Glands, hormones
- **Digestive**: GI tract, accessory organs
- **Renal**: Kidneys, fluid balance
- **Musculoskeletal**: Bones, muscles, joints

### Homeostasis

```python
# Negative feedback example: Thermoregulation
def thermoregulation(body_temp, set_point=37.0):
    """
    Maintain body temperature.
    """
    deviation = body_temp - set_point
    
    if deviation > 0.5:
        # Too hot: vasodilation, sweating
        return {'response': 'cooling', 'mechanisms': ['sweating', 'vasodilation']}
    elif deviation < -0.5:
        # Too cold: vasoconstriction, shivering
        return {'response': 'warming', 'mechanisms': ['shivering', 'vasoconstriction']}
    else:
        return {'response': 'normal'}

# Feedback types
feedback_types = {
    'negative': 'Counteracts change (most common)',
    'positive': 'Amplifies change (rare, e.g., childbirth)'
}
```
