epithelial Simple Squamous Endothelial Tissue
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
Simple Cuboidal Epithelial Tissue
The lumen receives the secretion produced by the cuboidal cells
The black circle is superimposed on the basement membrane which holds t
ogether 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)

Simple Columnar Epithelial Tissue
The fuzzyness on top of the simple columnar cells is caused by tiny microvilli.
found: i
n GI tract and uterus;
function: absorption of foods (microvilli); move sperm (cilia); secretion of mucus (goblet cells). Back to Epithelial Menu

Pseudostratified Epithelial Tissue
a nuclei of pseudostratified columnar cells

Stratified Squamous Epithelial Tissue
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. Back to Epithelial Menu
