1. Simple Epithelial Tissues:

For each tissue: we will look at structure first, then its function(s), and its location in the body based on the function the tissue performs.

A. Simple Squamous: Notice: one layer of cells (nuclei)=simple AND flat cells=Squamous.

Functions: *very thin and permeable *very slick

Location: *lines the inside of all blood vessels (endothelium) (Endo-inside)

*line the inside of the heart (endocardium)

Now think! Why would we want the inside of the heart and blood vessels to be slick?

Right! So that blood can just glide through! Think of yourself as a blood cell as you go down a water slide into the pool. You would want the surface of the slide to be slick right?

*form the walls of capillaries (the smallest BV) and are responsible for feeding the tissues and alveoli (air sacs of the lungs)

Capillaries and alveoli are only one cell thick and allow gases, nutrients, and waste to pass through.

OK…as you can see the structure of the tissue; relate its function to its location in the body.

This method helps you relate why the tissue is found in that location instead of just memorizing.
