1. INTEGUMENTARY SYSTEM – FILL IN BLANKS HUMAN ANATOMY & PHYSIOLOGY I

2. THE INTEGUMENTARY SYSTEM (THE SKIN) __CUTANEOUS___ membrane is your skin. Its superficial ___EPIDERMIS___ is composed of __KERATINIZING_ (becoming hard and tough) stratified squamous epithelium. The underlying _DERMIS_ is mostly dense (fibrous) connective tissue.

3. THE INTEGUMENTARY SYSTEM (THE SKIN) The skin is an _ORGAN_ system of its own. Integument means “_COVERING_”. The skin has many functions, most of which are _PROTECTIVE_.

4. THE INTEGUMENTARY SYSTEM (THE SKIN)  It _INSULATES_ and _CUSHIONS_ the deeper body organs and protects the entire body from _MECHANICAL_ damage (bumps and cuts).  _CHEMICAL_ damage such as from acids and bases.  _THERMAL_ damage such as extreme heat and cold.

5. THE INTEGUMENTARY SYSTEM (THE SKIN)  ULTRAVIOLET_ radiation from the sunlight and bacteria.  _PREVENTS_ water loss from the body’s surface.  _MINI_ _EXCRETORY_ system when urea, salts, and water are lost when we sweat.

6. THE INTEGUMENTARY SYSTEM (THE SKIN)  _MANUFACTURES_ several proteins important to immunity  _SYNTHESIZES_ vitamin D.  Contains _CUTANEOUS_ _SENSORY_ _RECEPTORS_ which are a part of the nervous system, contain tiny sensors for touch, pressure, temp, and pain.

7. THE INTEGUMENTARY SYSTEM (THE SKIN)  BACTERIAL_ damage prevented when _PHAGOCYTES_ ingest foreign substances and prevents then from reaching deeper body tissues.

8. STRUCTURE OF THE SKIN.  Includes the _EPIDERMIS_ which is superficial. Beneath that is called the _DERMIS_. These two are firmly connected, but when they become separated by friction or a burn, then a _BLISTER_ forms.

9. STRUCTURE OF THE SKIN.  Deep to the dermis is the _SUBCUTANEOUS_ _TISSUE_ or the _HYPODERMIS_ which is essentially _ADIPOSE_ tissue.

10. STRUCTURE OF THE SKIN.  This tissue serves as a _SHOCK_ _ABSORBER_ and _INSULATES_ the deeper tissues from extreme _TEMPERATURES_. It is also responsible for the _CURVES_ that are more for a woman’s body than mans.
