Some confusing terms...

Ok, some terms starting with "e" that are causing some confusion:

Epithelium/epithelial cells: Tissue that makes up the layer that covers the surface of organs, cavities, vessels and tubes in animals, like the surface of the gut (eg, villi of the ileum).

Endothelium:A type of epithelium that lines the inner surface of the blood vessels (eg, one cell thick capillary wall).

Epidermis/epidermal cells:Makes up the layer that covers the surface of plant parts, like the roots, stem and leaves.

Endometrium:Inner lining of the uterus that breaks down and is shed during menstruation. This lining thickens and is where the blastocyst implants.
