Introduction:
The integumentary system is a vital system. This system is responsible for several functions such as: maintaining boundaries, regulation of body temperature, and secreting waste materials. The skin has three layers from superficial to deep: Epidermis, Dermis, Hypodermis. The Epidermis has five layers: Stratified corneum, lucidium, granulosum, spinosum, and basale. The dermis has two layers: Papillary and reticular. Below are images of the integumetary system and its organs.

Functions- Maintain boundaries
- Regulates body temperature - Produces proteins - Stores water and fat - Helps excrete oils and waste materials - Bodily senses (Marieb, 2003) Organs FunctionsSkin
ImbalancesVariola Virus(Small Pox): This imbalances is caused by virus particles entering the lungs. This imbalance varies between ages, gender and ethnicity. This imbalance side effects are rashes, chills, body aches, and head aches.
(Paulson, 2010) Stretch Marks: Tearing of the reticular layer of the dermis. This imbalance typically happens when skin is stretched from gaining/losing weight. Common in pregnancy. Side affects: Itchiness. (Janowski, 2013) Blisters: Formed by rubbing, friction, exposure of heat, cold or chemicals. It is typically a small fluid filled bubble between the upper layers of the skin. The side affects include burning sensations(if burnt), itchiness, or irritation. ( Siddons, 2013) |
Microscopic AnantomyMicroscopic:
Hypodermis Layer: The inner most layer of skin. Made of adipose tissue. This layer acts as a cushion and stores energy and fat. Found in the organ skin. Keratinocytes: Keratinocytes produces keratin which are natural body proteins that strengthen the body and protects from environmental changes. Found in the organ skin. Lunula: Is the whitish crescent shaped figure in nails and toenails. It has no functions just a thick layer of tissue. Found in fingernails. Hair Shaft: The hair shaft is the part of hair projecting beyond the skin. This is found in hair. (Marieb, 2003) (Weis, 2004) ( Weis, 2004) (Clipart)
Gross AnatomyEpidermis Layer: The outer most layer of skin. This layer is composed of stratified squamous epithelial tissue. This layer helps to maintain boundaries and protect deeper layers of the skin. Found in the organ Skin.
Hair Follicle This is the actual hair found on top of your head skin, arms, legs and fingers. It keeps the body warm and protects it from UV rays. Cuticle: A u-shaped form of keratinized cells that protect the nail bed. ( Marieb, 2003)
