Question 11

simple squamous function+description

Answer 11

• single layer of flat cells that resembles a tiled floor when viewed from the apical surface; centrally located nucleus that is flattened and oval or spherical in shape
• present at sites where the processes of filtration, diffusion, and secretion occur. not found in body areas subject to wear and tear.

Question 12

simple cuboidal function+description

Answer 12

• single layer of cube-shaped cells; round, centrally located nucleus.
• secretion and absorption

Question 13

non-ciliated simple columnar

Answer 13

• single layer of non-ciliated column-like cells with oval nucleus near base of the cell, contains two types: columnar with microvilli at their apical surface and goblet cells
• secretion and absorption, secreted mucus serves as a lubricant for the linings of tracts

Question 14

goblet cells

Answer 14

a type of simple columnar, modified and secrete mucus at their apical surfaces. Provide mucus for digestive
