If the temperature of the skin drops too much (such as environmental temperatures below freezing), the conservation of body core heat can result in the skin actually freezing, a condition called frostbite. When the sweat evaporates from the skin surface, the body is cooled as body heat is dissipated. The skin and its derivatives (hair, nails, sweat and oil glands) make up the integumentary system.

It has a variety of additional functions; it may serve to maintain water balance, protect the deeper tissues, excrete wastes, and regulate body temperature, and is the attachment site for sensory receptors to detect pain, sensation, pressure, and temperature. How does the integumentary system interact with other systems? The skin and its accessory structures make up the integumentary system, which provides the body with overall protection.

Psoriasis of the nails: A skin condition that causes pitting, nail discoloration and other symptoms. Ringworm is a fungal infection that causes a ring-shaped rash on the skin. The integumentary system helps regulate body temperature through its tight association with the sympathetic nervous system, the division of the nervous system involved in our fight-or-flight responses. In addition to its barrier function, this system performs many intricate functions such as body temperature regulation, cell fluid maintenance, synthesis of Vitamin D, and detection of stimuli. This leads to the buildup of scaly, red, and itchy patches of skin.
