integumentary system

The integumentary system includes the skin, hair, nails, and glands, serving as the body's first line of defense. It protects internal organs from injury, infections, and dehydration, and helps regulate temperature. The skin also senses touch, pain, and temperature changes. Hair and nails provide additional protection and assist with sensory functions. Glands in this system produce oils and sweat, which help keep the skin healthy and cool. Overall, the integumentary system plays a critical role in safeguarding your body, maintaining homeostasis, and enabling sensory perception.
