P2 outline the structure of the main tissues of the body.

Simple Cuboidal

Simple cuboidal epithelium is a tissue in secretion organs. These include locations in the salivary glands, thyroid gland, as well as in the kidneys. This tissue is a single underlying layer of cuboidal cells beneath the epithelium of the organs.

Simple columnar

Columnar epithelial cells occur in one or more layers. The cells are cube shaped. The nuclei are cube shaped and are usually located near the base of the cells. Columnar epithelium forms the lining of the stomach and intestines. Some columnar cells are senses for things like smell, taste and noise such as in the nose, ears and the taste buds of the tongue.

Simple squamous

The functions of squamous epithelial cells are many. Some of the main ones include protecting the line passageways, covering the surface of various organs among others. They normally arrange themselves in a single layer.

Simple ciliated

Epithelial Simple ciliated are cells that contain tiny hair like structures which beat in synchrony. They are similar to Epithelial Columnar. Their main function is to move objects and materials around the body using their hairs.

Simple Compound

Compound tissue - Consists of more than 2 layers and the deepest layer rest on the basement membrane. Being multilayered, it doesn’t perform the role of secretion or absorption but functions as protective layer against mechanical, chemical, thermal and osmotic stress.

Simple keratinised

Keratinised epithelial cells are basically dead skin cells. These cells are useful in the body because they protect outside bacteria and viruses from passing through into the skin. There is no real function to keratinized cells; they just protect the newer skin inside. These cells usually ...
