Clemson BIOL 2220 Exam 2 (Tissues,
Membranes, Integumentary, Bone, Skeleton,
Joints) Questions and Answers 100% Pass
simple epithelial tissue - ✔✔- one cell layer thick
- function mostly in absorption and filtration
- found in areas that don't have a lot of friction
stratified epithelial tissue - ✔✔- more than one cell layer thick
- major function is in protection
- found in areas with lots of abrasion
pseudostratified epithelial tissue - ✔✔- looks like more than one cell layer thick because
of the nuclei but is only one cell layer thick
- greek pseudo means fake or false
- each cell has contact with the basal layer of the basement membrane
- sometimes apical surfaces are not equal
- found in areas with little movement
-ex. respiratory tract

,squamous - ✔✔flat
cuboidal - ✔✔- same length and width
- involved in secretion
columnar - ✔✔- greater length then width
- found in high numbers in the digestive and respiratory tract
transitional - ✔✔- characterized by a dome shape at the apical surface
- transitional epithelium line hollow storage organs like the bladder
- as the storage containers fill up, the dome shape flattens, changing the capacity of
storage vessel
- this allows for filling of the storage container (bladder) without the stretching of the
container.
- eventually the container fills enough and is stretched
general functions of epithelial tissue - ✔✔- established boundaries
- protection
- absorption
- filtration
- excretion

,- secretion
- sensory reception
EAT PROTEIN AND FAKE EXCERCISE SLUTY SISTER
establishes boundaries
- general function of epithelial tissue - ✔✔epithelial tissue acts as the limiting boundary
of the human organism
protection
- general function of epithelial tissue - ✔✔the epithelial tissue in the digestive tract
prevents us from digesting our own organs, and protect against the abrasive action of
food
absorption
- general function of epithelial tissue - ✔✔nutrients are absorbed through epithelial
tissue during digestion
filtration
- general function of epithelial tissue - ✔✔found mostly in the kidney
excretion
- general function of epithelial tissue - ✔✔we excrete metabolic wastes out of the
digestive system through epithelial tissue

, secretion
- general function of epithelial tissue - ✔✔glandular epithelial tissue secretes things
sensory reception
- general function of epithelial tissue - ✔✔- some cells in the epithelial tissue are
modified for sensory reception
- tactile/ touch sensory receptors in the skin allow for us to feel the ants crawling on our
body
boundaries of epithelial tissue - ✔✔- apical surface
- basal surface
apical surface - ✔✔exposed to the air/ free surface
basal surface - ✔✔- attached surface that is connected to something
- normally attaches epithelial tissue to connective tissue
the word surface is used to refer to... - ✔✔simple/ single cells
the word layers is used in reference to.... - ✔✔stratified cells
basement membrane - ✔✔- at the basal surface of epithelial tissue
- composed of the basal lamina and reticular lamina
basal lamina - ✔✔- part of basement membrane
