Root words
Tissue Tissue: Cells that are organized into groups and layers 4 Kinds: Epithelial, Connective, Muscle, Nervous Basement Membrane: Underside of tissue, nonliving layer
Tissue Epithelial Tissue: Tissue that covers body surface, organs, and glands. Used for protection, secretion, absorption, and excretion Lack blood vessels, divide frequently, tightly packed
Simple Squamous Epithelium
Simple Squamous Epithelium Consist of a single layer of tightly packed, flattened cells Form in the airs sacs of lungs, blood vessels, and body cavities Thin and delicate, easily damaged
Simple Cuboidal Epithelium
Simple Cuboidal Epithelium Cube-shaped cells, tightly packed Ovaries, kidneys, salivary glands, liver
Simple Columnar Epithelium
Simple Columnar Epithelium Elongated, single layer cells. Can contain Cilia: for movement of materials Female reproductive tubes, small and large intestines
Pseudostratified Columnar Epithelium
Pseudostratified Columnar Epithelium Single, elongated layer, but appear stratified because nuclei are located at different levels Line passages of respiratory system, trap dust and microorganisms
Stratified Squamous Epithelium
Stratified Squamous Epithelium Many layers, thick tissue. New cells push older ones further out Outer layer of skin, esophagus, vagina, anal canal
Stratified Cuboidal Epithelium
Stratified Cuboidal Epithelium Two-three layers of cube like cells Sweat glands, Salivary glands
Stratified Columnar Epithelium
Stratified Columnar Epithelium Several layers of elongated cells Male urethra
Transitional Epithelium
Transitional Epithelium Specialized to contract and expand based upon tension Bladder and uterus
Glandular Epithelium Cells that produce and secrete substances into ducts and body fluids Exocrine Glands: secrete their product on open surfaces (Skin, digestive tract) Endocrine Glands: Secrete into tissue fluid and blood
