Integumentary System
The skin has two
regions: the epidermis and the dermis. The hypodermis lies below the skin. The
epidermis, the outer layer of the skin, is made up of stratified squamous
epithelium. The dermis is composed
of irregular connective tissue and lies beneath the epidermis. The hypodermis is made up of loose
connective tissue and adipose tissue, witch insulates the body from heat and
cold.
Accessory
structures of the skin include hair, nails, and glands. Both hair and nails are produced by the
division of epidermal cells and consist of keratinized cells. Sweat glands are numerous and present
in all regions of the skin. (Sweating helps lower body temperature.) Sebaceous
glands are associated with a hair follicle and secrete sebum, which lubricates
and waterproofs hair and skin. Mammary glands produce milk in the breasts after
childbirth.
Skin
cancer occurs in three forms. Basal cell carcinoma and squamous cell carcinoma
can usually be surgically romoved. Melanoma is the most dangerous form of skin
cancer. The skin has regenerative
powers and can grow back on its own if a wound is not too extensive. The
severity of a burn depends on its depth and extent. First-degree burns affect only the epidermis.

Burns.
The severity of a burn depends on its depth and extent. First-degree burns affect only the epidermis
and a potion of the dermis.
Third-degree burns affect the entire epidermis and dermis. The Òrule of ninesÓ provides a means of
estimating the extent of a burn injury.
Effects
of aging. Skin wrinkles with age because the epidermis is held less tightly,
fibers in the dermis are fewer, and the hypodermis has less padding. The skin has fewer blood vessels, sweat
glands, and hair follicles.
Although pigment cells are fewer and the hair turns gray, pigmented
blotches appear on the skin.
Exposure to the sun results in many of the skin changes we associate
with aging.
Homeostasis. Skin protects the body from physical
trauma and bacterial invasion. Skin helps regulate water loss and gain, which
helps the urinary system. Also,
swear glands excrete some urea. The skin produces a precursor molecule that is
converted to vitamin D following exposure to UV radiation. A hormone derived from vitamin D helps
regulate calcium and phosphorus metabolism involved in bone development. The
skin contains sensory receptors for touch , pressure, pain, hot, and cold,
which help people to be aware of their surroundings. These receptors send
information to the nervous system.
The skin helps regulate body temperature. When the body is too hot,
surface blood vessels dilate, and the sweat glands are active. When the body is cold, surface blood
vessels constrict, and the sweat glands are inactive. Hyperthermia and
hypothermia are two conditions that can result when the bodyÕs temperature
regulatory mechanism is overcome.
With hypothermia, the body temperature rises above normal, and with
hypothermia, the body temperature falls below normal.

Warnings!
If burned, discomfort, pain, disfigurement, and possibly death,
may occur.
Dry skin is also discomforting.
If lying in the same position for a prolonged period of time
occurs, a bedsore will most likely appear.

Acne and Psoriasis are some complications of the skin due to
chemical imbalances.
Danger!
Severe burns are a danger to how well you skin is able to
protect itself from diseases and infections. Skin graphs are pertinent if the burn is severe enough to
were the skin is unable to grow newly and healthy again.
Operation
The operation of the integumentary system is to protect all the
muscles and organs in the body.
Safety Instructions
Wearing sun block is vital to having smoother, healthier skin
when old age arises. Also,
protection from UV rays, will prevent the likelihood of melanoma.
If the skin as acne, we recommend that you seek out a
dermatologist, before scarring takes place.
If there is any hair loss, Rogain is an excellent product to
look into if you which to restore your full head of hair.
Proper protection in all elements is strongly advised. i.e.
winter; scarf, mittens, boots, thick coats, lip balm, summer; sunscreen,
sunglasses, hats/visors.
Maintenance
To be done daily: showering/facial skin care
To be done weekly: application of lotion
To be done monthly: exfoliation or if any oddly shaped moles
appear, see a doctor to check if it is cancerous.
Yearly inspections: Dermatologist
