what is the body's primary energy reservoir

fat

32

cell junctions

connections between one cell & another

-adjacent cells are bound by fusion of the outer phospholipid layer of membrane
-seals off intercellular space

-patch that hold cells together
-serves to keep cells from pulling apart

endocrine
ex. thyroid, pituitary

43

where do exocrine/endocrine secrete

products into a duct/ hormones into the blood

44

modes of secretion (3)

merocrine
apocrine
holocrine

45

use vesicles that release their secretion by exocytosis

merocrine

46

lipid droplet covered by membrane & cytoplasm bud

apocrine

47
