ANATOMY

Detailed explanation-1: -The integumentary system includes the epidermis, dermis, hypodermis, associated glands, hair, and nails. 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.

Detailed explanation-2: -Nervous system: The skin transmits information from sensations through nerve receptors to the brain. These include the perception of pain, heat, cold, and others.

Detailed explanation-3: -The functions of the skin include: Protection against microorganisms, dehydration, ultraviolet light, and mechanical damage; the skin is the first physical barrier that the human body has against the external environment.

Detailed explanation-4: -Your integumentary system acts as a physical barrier-protecting your body from bacteria, infection, injury and sunlight. It also helps regulate your body temperature and allows you to feel skin sensations like hot and cold.

Detailed explanation-5: -Sweat glands in the skin allow the skin surface to cool when the body gets overheated. Thermoregulation is also accomplished by the dilation or constriction of heat-carrying blood vessels in the skin. Immune cells present among the skin layers patrol the areas to keep them free of foreign materials.
