Major Tissue Types

Epithelial Tissue Function
Epithelial tissues lines all body surfaces and cavities
Functions:
Special features of epithelial tissue:
Cells are __________________________
______________________ attached to ___________________, _______________________ is free.
_______________________– no blood supply. Nutrition and gases diffuse from underlying connective
tissue
Excellent ______________________ability. Contain multi- and uni-potent stem cells.
How does each special feature relate to the functions of the tissue?
1
Classifying Epithelial Tissue
Simple squamous epithelium
2
A single layer of ____________cells, specializing in rapid diffusion and filtration
Found in: alveoli of lungs, walls of capillaries, kidney glomeruli and serosae
3
Simple cuboidal epithelium
A single layer of
_______________________ cells
Found in: glands, kidney tubules, ovaries
Simple columnar epithelium A single layer of _______________ shaped cells Often contain mucus- producing ____________ ____________ and / or cilia Found in: digestive tract (unciliated), bronchi (ciliated), and uterine tubes (ciliated)
Pseudostratified columnar epithelium A single layer of cells ______________________
Often contain cilia and Goblet cells Found in: respiratory tract
4
Stratified Squamous Epithelium _____________________of epithelial tissue.
Flattened and atrophied (‘dead’) at the apical edge; but can be rounder at basal edge.
Apical edge sloughs off and is replaced.
Function: protection from wear & tear
Found in skin, mouth, esophagus
Transitional epithelium
Cells can ______________________, allowing the tissue to stretch.
Apical cells appear round when tissue is relaxed, and flat with tissue is stretched.
Found in urinary tract.
