Lumen = Open Space
Stratified Squamous Epithelium – Keratinized
Squamous cells are growing “down” into the connective tissue.
Problem = Inadequate blood supply to all epithelial tissue.
Simple Squamous Epithelial Tissue
Lumen = Air Space
Capillary = small blood vessel
Basement Membrane = to small to see!
Alveoli (SSE) have broken open, enlarging the lumen (air space)
Problem:Less surface area for O2 and CO2 exchange.
Simple Cuboidal Epithelium – allows for filtration of water and salts.
Lumen – collecting duct for excess water and salts.
Connective Tissue (very little)
Irregular growth of epithelial cells or connective tissue.
Problem:Ducts are improperly formed, leading to poor filtration of water, waste and salts.
Simple Squamous Epithelium – Provides smooth surface on interior of artery.
Lumen – inside of blood vessel
Smooth Muscle Tissue
Plaque and cholesterol are stored under the SSE.
Problems:Narrows artery, leaves interior of artery rough and decrease elasticity of artery.
