Functions of Epithelial Tissue

Back 1

Covers exposed surfaces.

Lines internal passageways

Forms secretory support

Front 2

What is the difference between old microscopes and modern microscopes

Back 2

Old microscopes only had one lens while modern microscopes have more than one.

Front 3

Endocrine glands secrete into...

Back 3

The interstitial fluid then the blood stream

Front 4

Functions of Epithelial Tissue (2)

Stratified Epithelia

Front 21

Stratified Epithelia are generally located in areas...

That need protection from mechanical or chemical stresses

Front 22

Examples of stratified epithelia

Back 22

The surface of the skin and the lining of the mouth

Front 23

How do epithelial cells replace or damages cells

Back 23

Through cell division

Front 24

A tight junction prevents

Back 24

Water and solutes from passing between cells
