Clemson BIOL 2220 Exam 2 (Tissues,
Membranes, Integumentary, Bone,
Skeleton, Joints) 2025 with verified
solutions
simple epithelial tissue - answer-✔- one cell layer thick
- function mostly in absorption and filtration
- found in areas that don't have a lot of friction
stratified epithelial tissue - answer-✔- more than one cell layer thick
- major function is in protection
- found in areas with lots of abrasion
pseudostratified epithelial tissue - answer-✔- 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 - answer-✔flat
cuboidal - answer-✔- same length and width
- involved in secretion
,columnar - answer-✔- greater length then width
- found in high numbers in the digestive and respiratory tract
transitional - answer-✔- 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 - answer-✔- established boundaries
- protection
- absorption
- filtration
- excretion
- secretion
- sensory reception
EAT PROTEIN AND FAKE EXCERCISE SLUTY SISTER
establishes boundaries
- general function of epithelial tissue - answer-✔epithelial tissue acts as the
limiting boundary of the human organism
protection
,- general function of epithelial tissue - answer-✔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 - answer-✔nutrients are absorbed through
epithelial tissue during digestion
filtration
- general function of epithelial tissue - answer-✔found mostly in the kidney
excretion
- general function of epithelial tissue - answer-✔we excrete metabolic wastes out
of the digestive system through epithelial tissue
secretion
- general function of epithelial tissue - answer-✔glandular epithelial tissue secretes
things
sensory reception
- general function of epithelial tissue - answer-✔- 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
, apical surface - answer-✔exposed to the air/ free surface
basal surface - answer-✔- attached surface that is connected to something
- normally attaches epithelial tissue to connective tissue
the word surface is used to refer to... - answer-✔simple/ single cells
the word layers is used in reference to.... - answer-✔stratified cells
basement membrane - answer-✔- at the basal surface of epithelial tissue
- composed of the basal lamina and reticular lamina
basal lamina - answer-✔- part of basement membrane
- noncellular sheet of glycoprotein
- basal layer secretes glycoprotein to help anchor the basal layer to the connective
tissue
reticular lamina - answer-✔- part of basement membrane
- collection of collagen fibers
- adds strength and integrity to the basement membrane
what two things work together to connect epithelial tissue to connective tissue -
answer-✔glycoproteins and collagen
