filtration, diffusion, osmosis, and secretion in serous membranes
simple squamous epithelium is present in the mesothelium in the ____ and the endothelium in _____
peritoneum; arterioles and venules
function of simple cuboidal epithelium
secretion and absorption
locations of simple cuboidal epithelium
- surface of ovary
- kidney tubules & smaller ducts of many glands
- secreting portion of some glands like the thyroid gland & ducts of some glands like the pancreas
- anterior surface of capsule of lens of the eye
- posterior pigmented epithelium of eye
epithelium that can be ciliated or nonciliated
simple columnar epithelium
simple columnar epithelium may contain mucus-secreting unicellular glands or _____
goblet cells
function of simple columnar epithelium
- absorption
- secretion of mucus, enzymes, or other substances
- ciliated type propels mucus (or reproductive cells) by ciliary action
_____ contains cells with microvilli at some locations
nonciliated simple columnar epithelium
location of nonciliated simple columnar epithelium
- lines gastrointestinal tract (from stomach to anus)

- some paranasal sinuses
- central canal of spinal cord
- ventricles of the brain
function of ciliated simple columnar epithelium
moves mucus and other substances by ciliary action
can be keratinized or nonkeratinized
stratified squamous epithelium
function of startified squamous epithelium
protects underlying tissues in areas subjected to abrasion
