25
Q

secrete directly into blood

A

endocrine glands

26
Q

secrete into body cavity or onto body surface

A

exocrine glands

27
Q

merocrine
apocrine
holocrine

A

3 types of secretion

28
Q

product is released from exocrine cell by vesicles through exocytosis

A

merocrine secretion method

29
Q

apical portion of cytoplasm packs with vesicles and is then shed

involves loss of cytoplasm and secretory product

gland cell regrows and repairs itself

A

apocrine secretion method

30
Q

superficial/apical cells in stratified glandular epithelium packs with secretory vesicles and then bursts

kills the cell

A

holocrine secretion method

31
Q

-structural framework
-transports fluids
-protect organs
-supports, surrounds, and connects other tissues
-stores energy
-immunity
