16
Q

simple columnar

A

Function: Secretion, absorption
Ex: internal surface of small intestine, digestive tract

17
Q

stratified squamous keratinized

A

protects underlying tissue, provides semi-waterproof membrane
Ex: soles of feet, palms of hand

18
Q

stratified squamous nonkeratinized

A

Protects underlying tissue, some absorption
Ex: tongue, lining of oral cavity

19
Q

pseudo-stratified epithelium

A
20
Q

What is the function of Epithelial tissue

A

secretion, protection, excretion, absorption, filtration, sensation

21
Q

secretion

A

process of movement of material internally ( enzyme, saliva, hormones)

22
Q

excretion

A

process of waste removal from the body (solid wastes, sweat, CO2)

23
Q

Endocrine gland

A
  • secrete into bodily fluids
  • no ducts: dense capillary net work
  • pineal, pituitary, ect.
24
Q

exocrine gland

A
  • secrete outside or into lumen
  • lumen: inside the digestive tract
25
Q

simple epithelium

A

one layer

26
Q

stratified epithelium

A

multi layered

27
Q

Squamous

A

thin and scaly

28
Q

cuboidal

A

squarish or round style cells

29
Q

columnar

A

tall narrow cells

30
Q

Pseudo-stratified columnar

A

Function: secretion, absorption
Ex: ciliated- lining of the trachea/ upper resp. tract
Non-ciliated: lining of the male reproductive duct
