What are the 4 basic tissue types?
Epithelial, Connective, Muscle, Nervous
-
Where can epithelium be found?
- Lining body structures
- outer surfaces
- surfaces of internal structures (lungs)
- inner surfaces (blood vessels)
-
- Simple Squamous Epithelium
- Function: Secretion, diffusion, filtration
- Location: Blood vessels, alveoli of the lungs.
-
- Simple Cuboidal Epithelium
- Function:
Secretion, absorption - Location: Kidney tubules, surface of ovaries
-
- Simple Columnar Epithelium
- Function: Secretion, absorption
- Location: Most of digestive tract, gall bladder.
-
- Goblet Cell(found among columnar epithelium)
- Function: Secretion
- Location: Digestive tract, respiratory tract.
-
- Ciliated Columnar Epithelium
- Function: Absorption, secretion.
- Location: Trachea, uterine tubes.
-
What are some of the functions of connective tissue?
- Connect parts
- Bind and support
- Protect
- Insulate
- Transportation
-
Connective tissues; types of fibers.
- Collagen: more rigid for support.
- Elastin: more elastic for movement.
- Reticular: in between, allows for support and movement.
