Epithelial Tissue Epithelial tissue forms a continuous layer or sheet

covering the entire body.

Protection, producing and releasing secretion as wellas absorbing nutrients all considered to be function ofthe epithelial tissue.

C. Simple Columnar Epithelium

A single layer of tall,cylindrical cells lining:

Small intestineDigestive tract

Oviducts

Contains mucus-secreting cells calledgoblet cell, it has a goblet-shaped and a clear

interior.

D. Stratified Squamous Epithelium

Non keratinizedItConsist of many layers,

the inner most layer

produces cells thatpushes the other cells

towards the surface and

become flattened.

Stratified Squamous Epithelium

( Keratinized)

As the cells begin to

flatten, die and accumulate

they form a protein calledkeratin.

They make the outer layer

of the epidermis tough,

protective & able to repelwater.
