● Columnar
Function of simple columnar (3)
○ Absorption
○ Protection
○ Secretion
Location of simple columnar
○ Lines digestive tract
○ Stomach
○ Small intestine
○ Large intestine
○ Proximal portion of anal canal
○ Gallbladder
○ Uterus and fallopian tube - presence of cilia to help
proper fertilized ovum to uterus
● Single layer of tall cells with nuclei at same level
● Often includes microvilli(bumpy extensions of apical surface,
responsible to increase absorption rate of tissues) and goblet
cells(produces mucus/lubrication as a form of protection)
