Due to a frying incident a man is covered in multiple levels of burns and the doctor is concerned about infection, dehydration, and body temperature
The integumentary system consists of the skin, hair, nails, glands, and nerves.
-
It also functions to retain body fluids, protect against disease, eliminate waste products, and regulate body temperature
Epidermis
The outermost layer of the skin, which is composed of squamous cells. This layer includes two distinct types: thick skin and thin skin.
Stratum granulosum
A layer of rectangular cells that become increasingly flattened as they move to the surface of the epidermis.
-
Stratum lucidum
A thin, flattened layer of dead cells. Not visible in thin skin.
Stratum basale
The innermost layer of elongated column-shaped cells. It consists of basal cells that produce new skin cells.
Stratum corneum
The top layer of dead, extremely flat cells. Cell nuclei are not visible.
Types of burns
Second-degree
involve the epidermis and part of the lower layer of skin, the dermis
he burn site looks red, blistered, and may be swollen and painful
-
First-degree
affect only the outer layer of skin, the epidermis
The burn site is red, painful, dry, and with no blisters.
-
Fourth-degree
involves injury to deeper tissues, such as muscle, tendons, or bone.
-
-
-
Critical burns are potentially life threatening, disfiguring, and disabling
Unfortunately, it often is difficult to tell if a burn is critical
-
Dermis
The thickest layer of the skin, which lies beneath and supports the epidermis
-
-
Sweat glands
Regulate body temperature by transporting water to the skin's surface where it can evaporate to cool down the skin.
Sensory receptors
Nerve endings that transmit sensations such as touch, pain, and heat intensity to the brain.
-
Collagen
Generated from dermal fibroblasts, this tough structural protein holds muscles and organs in place and gives strength and form to body tissues.
-
Elastin
Generated from dermal fibroblasts, this rubbery protein provides elasticity and helps make the skin stretchable.
It is also found in ligaments, organs, muscles, and artery walls.
Hypodermis
The innermost layer of the skin, which helps insulate the body and cushion internal organs
The hypodermis also connects the skin to underlying tissues through collagen, elastin, and reticular fibers that extend from the dermis.
-
-
Other components of the hypodermis include blood vessels, lymph vessels, nerves, hair follicles, and white blood cells known as mast cells.
Mast cells protect the body against pathogens, heal wounds, and aid in blood vessel formation.
