πŸ“š Quick Study Guide

  • πŸ”¬ The integumentary system includes the skin, hair, and nails.
  • πŸ›‘οΈ It acts as a protective barrier against the external environment.
  • 🌑️ Temperature regulation is a key function, achieved through sweat glands and blood vessel dilation/constriction.
  • πŸ–οΈ Sensory reception allows us to perceive touch, pressure, temperature, and pain.
  • πŸ’§ The skin prevents water loss and dehydration.
  • β˜€οΈ It synthesizes vitamin D when exposed to sunlight.
  • πŸ—‘οΈ Limited excretion of waste products occurs through sweat.
