Simple Squamous Epithelial

Simple Squamous Epithelial
a nucleus of a cell forming the alveolus wall
b nucleus of a cell forming the capillary
wall c red blood cells inside capillary that
will carry exchanged gases between the
lungs and blood d cell that forms the
large circle of simple squamous forming
the alveolus. found line lungs line blood
vessels (endothelium) function adapted for
osmosis, diffusion and
secretion
4
Simple Cuboidal Epithelial

• The lumen receives the secretion produced by the
  cuboidal cells
• The black circle is superimposed on the basement
  membrane which holds together a circle of
  cuboidal cells.
• Found line kidney tubules cover ovaries
  glands
• Function adapted for secretion of fluid like
  mucus or enzymes absorption (microvilli increase
  surface area)

5
Simple Columnar Epithelial

• The fuzzyness on top of the simple columnar cells
  is caused by tiny microvilli.
• Function absorption of foods (microvilli) move
  sperm (cilia) secretion of mucus (goblet cells).

Stratified Squamous Epithelial
a bracket is around the many rows of cells that
belong to the stratified squamous epithelial
tissue b dead surface layers Found
epidermal layer of skin lines mouth, esophagus,
vagina and anal canal Function wall of
protection against waterloss, abrasion infection,
etc.
10
Transitional Epithelial
a collapsed layers of the transitional cells
b surface of the collapsed ureter Found
walls that line the urinary tract and bladder
Function able to stretch when an organ expands
