Tissue Types
| TYPE/DESC | FUNCTION | LOCATION |
|---|---|---|
| Simple squamous epithelium Single layer, flattened cells | Filtration, diffusion, osmosis, covers surface | Air sacs of lungs, walls of capillaries, linings of blood and lymph vessels, part of the membranes lining body cavities and covering viscera |
| Simple cuboidal epithelium Single layer, cube-shaped cells | Protection, secretion, absorption | Surface of ovaries, linings of kidney tubules, and linings of ducts of certain glands |
| Simple columnar epithelium Single layer, elongated cells | Protection, secretion, absorption | Linings of uterus, stomach, and intestines |
| Pseudostratified columnar epithelium Single layer, elongated and variously-shaped cells | Protection, secretion, movement of mucus and substances | Linings of respiratory passages |
| Stratified squamous epithelium Many layers, top cells flattened | Protection | Superficial layer of skin and linings of oral cavity, vagina, and anal canal |
| Stratified cuboidal epithelium 2 or 3 layers, cube-shaped cells | Protection | Linings of ducts of mammary glands, sweat glands, salivary glands, and pancreas |
| Stratified columnar epithelium Top layer of elongated cells, lower layers of cube-shaped cells | Protection, secretion | Part of the male urethra and lining of larger ducts of excretory glands |
| Transitional epithelium Many layers of cube-shaped and elongated cells | Stretchability, protection | Inner lining of urinary bladder and linings of ureters and part of urethra |
| Epithelial Lack blood vessels, cells readily divide, cells are tightly packed | Protect, secrete, absorb, excrete | Cover body surface, cover and line internal organs, compose glands |
| Connective Mostly have good blood supply, cells are farther apart than epithelial cells, with extracellular matrix in between | Bind, support, protect, fill spaces, store fat, produce blood cells | Widely distributed throughout the body |
| Muscle Able to contract in response to specific stimuli | Generate forces for movement | Able to contract in response to specific stimuli |
| Nervous Cells communicate with each other and other body parts | Conduct impulses for coordination, regulation, integration, and sensory reception | Found in brain, spinal cord, nerves |
