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

# 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)'
}
