T/F: exocrine glands can be unicellular or multicellular

A

true

24
Q

examples of unicellular exocrine glands

mucous cells
goblet cells

both produce mucin

25
Q

multicellular glands

A

composed of duct and secretory unit
surrounded by connective tissues

classified by structure and mode of secretion

branched ducts

28
Q

tubular exocrine gland

A

secretory cells form a duct

29

alveolar exocrine gland

A

secretory cells form sacs

30
Q

merocrine glands

secrete products by exocytosis as secretions are produced

sweat
pancreas

31
Q

holocrine glands

A

accumulate products within, then rupture

sebaceous oil glands

32
Q

apocrine glands

A

accumulate products within, but only apex ruptures

four main classes of connective tissues

A

connective tissue proper
cartilage
bone
blood

34
Q

function of connective tissues

binding and support
protecting
insulating
storing reserve fuel
transporting substances (blood)
