Stratified squamous epithelium consists of multiple cells which are stacked in layers whose membrane is selectively permeable and provides protection against friction and microbial invasion(e.g. bacteria) and desiccation(i.e. deprived of moisture).

Stratified squamous epithelium contain columnar cuboidal cells which gradually flatten towards the surface.

This type of epithelium exist in two forms:
1. Keratinized stratified epithelium- found in outer dry surfaces of body such as the skin and nails.

2. Non-keratinized stratified epithelium- found on moist surface that will likely go through wear and tear, such as the mouth cavity, tongue, pharnyx and esophagus. 

Here is a diagram showing the layers of stratified squamous epithelium.]]> 2016-11-01 19:35:55 UTC https://padlet.com/epithelialtissue/emkherpvk37v/wish/134612499 epithelialtissue https://padlet.com/epithelialtissue/emkherpvk37v/wish/134612645 This type of epithelium are one cell thick as opposed to stratified squamous squamous epithelium. These consist of single layer of flattened cells resting on connective tissues. 

Simple squamous line the surface of arteries and veins mostly referred to as the endothelium and it also lines capillaries and the alveoli for gaseous exchange. ]]> 2016-11-01 19:36:38 UTC https://padlet.com/epithelialtissue/emkherpvk37v/wish/134612645 epithelialtissue https://padlet.com/epithelialtissue/emkherpvk37v/wish/134616483 It is also found in the kidney specifically in the Bowman's capsule which allows for an easier and faster filtration of the blood.]]> 2016-11-01 19:51:01 UTC https://padlet.com/epithelialtissue/emkherpvk37v/wish/134616483 2288194p https://padlet.com/epithelialtissue/emkherpvk37v/wish/134619606 2016-11-01 20:05:51 UTC https://padlet.com/epithelialtissue/emkherpvk37v/wish/134619606 https://padlet.com/epithelialtissue/emkherpvk37v/wish/134619638 The objective lens is 400x]]> 2016-11-01 20:06:06 UTC https://padlet.com/epithelialtissue/emkherpvk37v/wish/134619638 2288194p https://padlet.com/epithelialtissue/emkherpvk37v/wish/134619904 Animal tissue that lines the surface of the body and  covers internal organs  and cavities. ]]> 2016-11-01 20:07:16 UTC https://padlet.com/epithelialtissue/emkherpvk37v/wish/134619904 https://padlet.com/epithelialtissue/emkherpvk37v/wish/134620028 The objective lens is 630x]]> 2016-11-01 20:07:54 UTC https://padlet.com/epithelialtissue/emkherpvk37v/wish/134620028 2288194p https://padlet.com/epithelialtissue/emkherpvk37v/wish/134620105 2016-11-01 20:08:18 UTC https://padlet.com/epithelialtissue/emkherpvk37v/wish/134620105 2288194p https://padlet.com/epithelialtissue/emkherpvk37v/wish/134620294 Cells of cuboidal epithelium have the shape of a dice and  are joined to form a sheet.

Cilia appears in the apical surface of these cells and its main function is to form a mucous membrane to protect lines for entrance of undesirable components.
