Recap

Where do you think Epithelial Tissues are found?

It is the covering or protective tissues in the animal body

Small amound of cementing material, almost no intercellular space

It covers most of the organs and cavities within the body, while also forming a boundary to keep different body systems separate

'Epi', a greek word, meaning 'above' or 'on top of''

___

It is the covering or protective tissues in the animal body

Recap of Epithelial tissues

Let's learn more!

Simple squamous epithelium

It's also found in the lining of the blood vessels

Simple Squamous is found in the lung alveoli

Theses cells are extremely thin and flat and form a delicate lining. In cells lining blood vessels or lung alveoli, where transpotation od substance occurs through a selectively permeable suface, the simple squamous epithelium is found.

Stratified squamous epithelium

Since they are arranged in a pattern of layers, the epithelium is called Stratified Squamous Epithelium

_________

A stratified epithelium is an epithelial tissue composed of more than one layer of epithelial cells. A stratified squamous epithelium is a stratified epithelium in which the topmost layer is made up of squamous (flattened and scale-like) epithelial cells.The oesophagus and the lining of the mouth are covered with squamous epithelium. The skin, which protects the body, is also made of squamous epithelium.

STRATIFIED SQUAMOUS EPITHELIUM

Simple and Stratified Squamous

Stratified Squamous Epithelium

Stratified Squamous Epithelium contains several cell layers.

Simple Squamous Epithelium

Simple Squamous Epithelium contains a single cell layer.
