In zootomy, the integumentary system is the external covering of the body, comprising the skin, hair, feathers, Scale (zoology), Nail (anatomy), sweat glands and their products (sweat and mucus). The integumentary system has a variety of functions; in animals, it may serve to waterproof, cushion and protect the deeper tissues, excrete wastes, regulate temperature and are the location of sensory receptors for pain, pressure and temperature. The name derives from the Latin integumentum, which means 'a covering'.

As an organ system The integumentary system is often the largest organ (anatomy) of an animal by surface area. It distinguishes, separates, protects and informs the animal with regard to its surroundings. Small-bodied invertebrates of aquatic or continually moist habitats Respiration (physiology) using the outer layer (integument). This gas exchange system, where gases simply diffuse into and out of the interstitial fluid, is called integumentary exchange.

Anatomy The cutaneous membrane (skin) and its accessory structures (hair, scales, feathers, nails, exocrine glands) make up the integumentary system.

There are three layers of skin:

Epidermis

Dermis

Subcutis

Below the dermis, the subcutis acts to protect underlying muscles, Tissue (biology), and other Organ anatomy). Hair on the surface of the skin helps maintain body temperature and filter out harmful particles.

Cutaneous glands include:

Sweat glands (also known as sudoriferous glands) - excrete sweat to regulate temperature
Sebaceous glands - oil-producing glands that keep skin and hair moist and soft
Ceruminous glands - glands of the ear canal that produce earwax
Mammary glands - milk-producing glands located in the breasts.

Layers Epidermis The epidermis is the thin outer layer of skin that contains melanin which gives skin its color and allows for the skin to tan. Carotene, and oxygen-rich hemoglobin also contributes to the color of skin. The epidermis also encompasses the protein keratin which stiffens epidermal tissue to form finger nails. The outermost layer consists of 25-30 layers of dead cells. Further levels include:

Scaly Cells form the surface of the skin

Melanocytes give the skin color

Langerhans cells are formed in the bone marrow and work to fight infection

It is divided into the following sub-layers:

Sublayers Epidermis is divided into the following 5 sublayers or strata:

Stratum corneum

Stratum lucidum.....

Stratum granulosum

Stratum spinosum

Stratum germinativum (also called "stratum basale")

Dermis The dermis is the bottom-most, thick inner layer of skin, which comprises blood vessels, connective tissue, nerves, lymph vessels, sweat glands and hair shafts. It has two main layers:

Upper Papillary: Contains touch receptors which communicate with the central nervous system and is responsible for the folds of the fingerprints

Lower Reticular: Made of dense elastic fibers that house the hair follicles, nerves, and gland

the penis has an extra layer of skin known as the penile dermis. it is very sensitive.

Functions The integumentary system has multiple roles in homeostasis. All body systems work in an interconnected manner to maintain the internal conditions essential to the function of the body. The skin has an important job of protecting the body and acts somewhat as the body’s first line of defense against infection, temperature change or other challenges to homeostasis. Functions include:

Protects the body’s internal living tissues and organs
Protects against invasion by Infection organisms
Protects the body from dehydration
Protects the body against Weather in temperature
Helps Excretion waste materials through perspiration
Acts as a receptor for touch, pressure, pain, heat, and cold (see Somatosensory system)
Protects the body against sunburns
Generates vitamin D through exposure to ultraviolet light
Stores water, fat, and vitamin D

Diseases and injuries The specialized treatment of the integumentary system is performed by Dermatology. Possible diseases and injuries to the human integumentary system include:

Rash
Blister
Acne vulgaris
Keratosis pilaris
Athlete's foot
Infection
Calcinosis cutis
Sunburn
Keloid
Scabies
