Pseudostratified epithelium is a single layer of cells that appears stratified due to the varying heights of the cells' nuclei. Therefore, there is only one layer of cells in pseudostratified epithelium.
Simple epithelium is characterized by being only one cell layer thick. It is found in areas where absorption, secretion, and filtration occur.
Epithelium consists of tightly packed cells that form a protective barrier against physical and chemical damage. Simple columnar epithelium is better suited for absorption and secretion functions rather than for protection. Epithelium is more closely packed and provides a more effective barrier compared to simple columnar epithelium.
This is a cell layer of epithelial tissue which is composed of cells which are wider than they are tall. The 'simple' means its one cell layer thick and the 'squamous' means the cells are wider than they are tall. Examples of areas where this type of cell layer include the outer surface of most body organs, the vascular system and the bowmans capsule in the kidney.
There is different types of squamous epithelium: simple and stratified. The function of simple squamous epithelium:It is good for the passage of materials via diffusion. For example, it forms the tiny air sacs of the lungs and the walls of capillaries. It also forms the smooth, friction-reducing interior lining of the heart, blood vessels, thoracic cavity, and abdominal cavity. The function of the stratifed squamous epithelium: It functions to protect underlying tissues in areas subjected to abrasion. The keratinized type forms the outermost layer of the skin, where it functions to prevent water loss. The nonkeratinized variety forms the moist linings of the mouth,esophagus, anus, vagina.
stratified squamous epithelium
The tracheal epithelium is thick and has the appearance of more than 1 layer of cells. The tracheal epithelium gives an optical illusion of being pseudostratified due to the nuclei of cells on different levels, thus making it look multi layered.

Simple epithelium is characterized by being only one cell layer thick. It is found in areas where absorption, secretion, and filtration occur.
Simple epithelial tissues consist of a single layer of cells, while stratified epithelial tissues have multiple layers of cells. Simple epithelial tissues are found in areas where there is minimal wear and tear, while stratified epithelial tissues are found in areas subjected to more abrasion and mechanical stress.
Simple squamous epithelium is only a single cell layer thick and lines body cavities such as the peritoneum, pleura, and pericardium. It is involved in processes such as filtration, diffusion, and osmosis.
The mucosa layer of the stomach, which is composed of epithelium, lamina propria, and muscularis mucosae, varies in thickness but is typically around 0.5mm. The submucosa layer is usually around 1mm thick, the muscularis externa layer can be up to 2-3mm, and the serosa layer is around 0.1mm thick.
They walls are a single layer of squamous epithelial cells.
