The fingernails and toenails belong to which body system?

The fingernails and toenails are part of the integumentary system, which is one of the body's major systems responsible for protecting the body from external harm, regulating body temperature, and providing sensory information. This system includes not only skin and nails but also hair and glands. Nails specifically serve to protect the tips of fingers and toes, enhance sensitivity, and assist with gripping objects.

The integumentary system plays a crucial role in overall health as it acts as a barrier to pathogens and helps prevent fluid loss. Understanding this system is essential in fields related to nail technology, as it underlines the significance of maintaining healthy nails for both aesthetic and functional reasons.
