Hair, Skin, Nails, and how to keep them youthful

The integumentary system is the body's biggest organ, and comprises the epidermis, dermis, hypodermis, related glands, hair, and nails. The integumentary protects and maintains the internal body environment by forming a physical barrier between the exterior and internal environments. The integumentary system plays a number of responsibilities in keeping the body in balance. To keep the internal conditions necessary for the body's operation, all of the body's systems operate together. The skin, which is the most important tissue of the integumentary system, protects the body and serves as the body's first line of defense against infection, temperature changes, and other disruptions of homeostasis. Its main functions include:
• Protects the body's interior organs and tissues.
• Prevents infectious agents from invading.
• Prevents dehydration of the body.
• Maintains homeostasis by protecting the body from sudden temperature swings.
• Carries out perspiration that aids in the excretion of waste items.
• Acts as a touch, pressure, pain, heat, and cold receptor (somatosensory system).
• Produces melanin that protects the body from the sun.
• Makes vitamin D upon exposure to UV radiation.
• Provides storage for water, fat, glucose, and vitamin D.
• Controls the body's temperature.
