Epithelial Tissue Terms List 2 Flashcards
Epithelial tissue
Tissue that lines the internal and external surfaces of the body
Simple squamous
Location, Function
Single layer flat, irregular cells
Locations: lung alveoli, serous membranes, blood vessel linings
Function: filtration, diffusion
Simple cuboidal
Location, function
Single layer cube shaped cells
Location: ducts of glands, kidney tubules
Function: secretion, absorption
Simple columnar
Location, function
Single layer column shaped cells
Location: intestinal lining
Function: absorption secretion
Stratified squamous keratinized vs non keratinized
Location, function
Multiple layers flat irregular cells
Location: skin, mouth, esophagus
Function: protection
K: more protection, waterproof, makes up epidermis of skin
Non K: less protective, lines mouth, esophagus, vagina
Pseudostratified columnar with cilia
Location, function
Single layer looks like stratified column shaped cells
Location: respiratory lining
Function: Protection, secretion, cilliated(move fluid)
Transitional
Location, Function
Multiple layers cuboidal/columnar cells
Location: bladder, ureters
Function: stretches
Cilia
Move water reactive to the cell
Microvilli
Increase surface area for diffusion
Goblet cells
Cell that secretes mucins
Keratin
Protein on epithelial cells that line inside outside surfaces of the body
