Answer 2

Answer:

Explanation:

Human body has 4 different types of tissues.

A “tissue” in simple terms is a bunch of cells.

They are formed by a combination of similar cells so as to have same physiological function in body.

Specific type of tissue has the same function in almost all of the higher animals.

These tissues together form the organs in the body.

They serve many purposes in the body and are differentiated to carry out special physiological functions.

Based on their physical structure and function, tissues of the body are differentiated as

Types of tissues

Epithelial tissue

Connective tissue

Muscular tissue

Nervous tissue.

Epithelial tissue: This tissue is an upper most tissue covering all the organs or body. This tissue based on need is of different types as simple epithelium, squamous epithelium, columnar epithelium etc.

This is further classified as

Simple epithelium

Stratified epithelium.

epithelium

By Mdunning/wikicommon

Simple epithelium is one which has a single layer of epithelial cells. It is present at sites where filtration or diffusion of substances is necessary. It is found in the nephron of kidney for filtration of blood, for diffusion of oxygen from lungs to blood. This type of single layer of epithelium is so thin and offers least resistance for transfer of molecules from one side to another.

Based on the shape of cells in this layer, it is further differentiated as simple squamous epithelium, simple cuboidal epithelium and simple columnar epithelium.

Stratified epithelium is a multi layered epithelium. This is differentiated based on the upper most layer and also the shape of cells in bottom layers.

The upper layer cells might be keratinised, dehydrated to protect from heat, microbes, wear and tear, chemicals etc. This type of layer is seen in skin.

In most other types of stratified epithelium, the upper layer is non-keratinised.

Based on the shape of lower layer cells, the epithelium is again differentiated as stratified squamous epithelium, stratified cuboidal epithelium, columnar stratified epithelium and psuedostratified columnar epithelium.

There is another type called transitional epithelium. This type of tissue is present in urinary bladder. The Cells are cuboidal or columnar in relaxed state. But when there is load, they stretch and become flat to accommodate the substance (urine).

There is one more type of epithelium i.e. is glandular epithelium which are present in glands.

Types of simple epithelium tissues:

Simple squamous epithelium: As the name indicates, this is a single layer of squamous shaped epithelium cells.

Types of tissues

2. Simple cuboidal epithelium has single layer of cuboid shaped cells.

3. Simple columnar epithelium has single layer of long column shaped cells
