2) List at least four characteristics that distinguish epithelial tissues from other types of tissues.

Epithelia are composed almost entirely of cells, have specialized contacts, have a free apical surface and a lower basal surface, are supported by underlying connective tissue, are avascular but innervated, and have a high capacity for regeneration.

1) Describe the classification of epithelial tissues.

Epithelia may be simple (single fayered) or stratified (in more than one layer). The cells that form it may be flat and plate like (squamous), roughly square (cuboidal), or tall and slender (columnar).

3). Is epithelium vascularized? How do nutrients and oxygen reach epithelium?

Epithelium is not vascularized; meaning capillaries do not directly reach its cells. It exchanges substances by diffusion with the connective tissue located under it.

5). What is the difference between simple squamous, simple cuboidal, and simple columnar epithelial tissues?

Simple squamous cells are flat, simple cuboidal cells are cube shaped, and simple columnar cells are taller and longer. They all just have one layer

4). How different is simple squamous epithefium from stratified squamous epithelium? Where are they found in the human body?

Simple squamous epithelium is made of a single layer of flat cells. Stratified squamous epithefium is made of flat cells placed in several layers. Simple squamous epithelium is found in pulmonary alveoli. Stratified squamous epithelium can be in the mouth, esophagus and vagina. It is also the epithelium of the skin.

3) What type(s) of epithelial tissue can be found in the sweat glands?

Stratified Cuboidal

2) This is the sheet of tissue between the epithelium and the connective tissue below it

basal lamina

1) The smallest diameter blood vessels, capillaries are comprised of

simple squamous epithelium

4). What would be found as skin covering?

stratified squamous (keratinized) epithelium
