- mesothelium
- endothelium
d. What other organs contain this tissue type?
- epididymis, ducts of glands, male urethra
- surface of ovaries and lens of eye; retina of eye; kidney tubules, ducts of glands
- air sacs of lungs, glomerular, capsule of kidneys, inner surface of tympanic membrane
- GI tracts, ducts of glands, gallbladder
e. What is the function of this tissue?
- Protects against abrasion, water loss, UV radiation, foreign invasion, defense against microbes
