Histology (epithelial)

simple squamous epithelium

barrier where gasses/fluids can be exchanged; produces serous fluid

pseudostratified columnar epithelium

secretes mucus and propels it with ciliary motion

simple cuboidal epithelium

absorbs and secretes mucus and other substances; located in the kidney tubules and lower respiratory passages

stratified squamous (non-keratinized)

protects against mechanical stresses and microorganisms; located in the mouth, pharynx, esophagus, and vagina

stratified columnar epithelium

protection, some absorption and secretion; found in the ducts of certain glands and the male urethra

transitional epithelium

protection, gives tissues added distensibility; found in the bladder

simple squamous epithelium

found in the air sacs of the lungs, inner lining of ventral cavities/blood vessels, and parts of the kidneys

simple columnar epithelium

absorbs and secretes mucus and other substances & propels eggs through the uterine tube

pseudostratified columnar epithelium

found in the nasal cavity, upper respiratory passages, and parts of the male urethra

stratified squamous (keratinized)

protects against stress and microorganisms and prevents water loss through skin; found in the epithelium

simple columnar epithelium

found in the lower digestive tract, uterine tube, gallbladder, and certain kidney tubules

stratified cuboidal epithelium

some absorption and secretion; found in the ducts of sweat glands

characteristics of epithelial tissues

more cells than ECM, cover and line surfaces, avascular, regenerate easily (due to friction)

functions of epithelial tissues

protection, absorption, filtration, secretion, excretion
