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.
