• Integumentary System - Functions

  • Provides protection
  • Regulates temperature
  • Controls water loss
• Is skin considered an organ?

  Yes
• Homeostasis is the tendency to maintain a relatively constant internal environment

  • Allows organisms to survive, ensuring optimal conditions for coordination within and between organ systems
• Negative Feedback is

  • how the body maintains homeostasis from body temp
  • brings the body back to optimal temperature when temperature shifts
