|
Single layer of square or round cells
Arranged around a central canal Location: Liver, glands, kidney tubules Functions: Absorption & Secretion |
|
|
Simple Columnar Epithelium
|
Single layer of tall narrow cells
Goblet cells Often has microvilli Location: Intestines, stomache Functions: Absorption, secretion |
|
|
Pseudostratified Columnar epithelium
|
Some cells do not reach surface
Goblet cells ciliated Location: Trachea Functions: Secretes & propels mucus |
|
|
Stratified Squamous Epithelium - Keratinized
|
-Multiple cell layers
-Layer of dead squamous cells -Living epithelial cells -Has Areolar Tissue -Locations: Epidermis -Functions: Resists Abrasion, waterproof |

Cartilage
(Connective Tissue) |
Hyaline
Elastic Fibrocartilage Produced by chondroblasts; become trapped in lacunae in the matrix and become chondrocytes. |
|
|
