Question 33

FUNCTIONS OF EPITHELIAL TISSUE

Answer 33

provide physical protection, control permeability, provide sensation, produce specialized secretions

Question 34

can be regulated and modified in response to stimuli ex: hormones can affect transport across epithelia, physical labor forms **_calluses_** on skin)

Answer 34

functions of epithelial tissue - control permeability

Question 34

can be regulated and modified in response to stimuli ex: hormones can affect transport across epithelia, physical labor forms **_calluses_** on skin)
