Answer 9

simple is single layer stratisfied is multipule layer

Answer 13

true

Question 14

what does simple squamous cells look like?

Answer 14

irregularly shaped puzzle pieces

Question 15

where can simple squamous cells be found?

Answer 15

in passageways and arias of absorbtion

Question 16

how can simple squamous epithelium be separated?

keratenaized

non keratinized

Question 18

what does cuboidal cells look like?

Answer 18

cubes

Question 19

where is simple cuboidal epithelium found?

Answer 19

absorbtion occurs

eg. kidney tubules or where secreations happen thyroid gland

Question 20

what are transitional epethelium?

Answer 20

unusual stratisfied epethelium
allows for stretching
found in the urinary bladder

Question 21

what does culumnar epethelium look like?

Answer 21

columns

Question 22

where can simple columnar epethelium be found?

Answer 22

where absorbtion and secreations takes place

eg. small intestine, gall bladder and stomach

Psoudostratisphied coloumnar epethelium is often found in the…

Answer 23

air passageways and nasal cavity

Question 24

where is stratisfied culumnar epethelium found?

Answer 24

rare and found in ducts

eg. saliva glands

Question 25

what are the three processes to secreate fluid onto a epethelial surface?

Answer 25

merocrine secreations a pro rinse secreations holocene secreations

Question 26

how do merocrine secreations work?

Answer 26

exocytosis

Question 27

what is involved with aprocrine secreations?

Answer 27

loss of secreatory product and cytoplasm

Question 28

what happens with holocene secreations?

Answer 28

become packed with secreations then burst

Question 29

word association for merocrine secreations?

Answer 29

mero= mucus vesicles with water
