Document Summary

Epithelia: shape, covering tissue wherever there is an organ its lined with. The order isn"t too important: layers: The more stratified, the less diffusion occurs. Protection, difficult to transmit gasses, toxins, nutrients. Squamous: squashed, wider than they are tall squamous is a common term in anatomy and it actually means scale-like, not squashed usually in an area of harsh environment, maximizes diffusion. Cuboidal: cube, as wide as they are tall. Involved in absorption and secretion many of the endocrine glands because they are involved in secretion. Columnar: column, taller than they are wide. When you see something cross two layers of the body, you will have a simple tissue ex: alveoli: the skin is made up of a stratified layer of epithelial tissue. Gets blood supply from neighbouring cells and if it needs to get blood from connective tissue it does this by diffusion.
