Epithelial cells

simple squamous epithelium

Protected regions with absorption or slippery surface; kidney tubules, alveoli, lining of blood and lymphatic vessels, inner surface of the heart

simple squamous epithelium

Allows materials to pass through easily by diffusion and filtration, while secreting alubricating substance

simple cuboidal epithelium

limited protection; where secretions or absorption takes place; glands and ducts

simple cuboidal epithelium

secretes enzymes and buffers

simple columnar epithelium

offer some protection; may be in areas of absorption and secretion; line digestive and urinary tracts

simple columnar epithelium

can be ciliated in bronchi

stratified squamous epithelium

where mechanical stresses are severe; surface of skin or inside of mouth

stratified squamous epithelium

protects against abrasion

stratified cuboidal epithelium

certain ducts and along transition zones in body tracts; sweat, salivary, and mammary glands

stratified cuboidal epithelium

Protective tissue

stratified columnar epithelium

certain ducts and along transition zones in body tracts; male urethra and some glands

stratified columnar epithelium

Protective tissue

pseudostratified columnar epithelium

Areas of protection and secretion; portions of respiratory and male urinary tract

pseudostratified columnar epithelium

Columnar shaped with varying nuclei placement which gives it a non-uniform, layered appearance, but is NOT stratified; typically have cilia

transitional epithelium

areas that need to withstand considerable stretching; urinary system

transitional epithelium

stratified; appear flattened

epithelial tissue

Tissue that covers outside of the body and lines organs and cavities

epithelial tissue

constant regeneration, free apical surface; attached to basement membrane; avascular

connective tissue

A body tissue that provides support for the body and connects all of its parts

connective tissue

surrounded by ECM varying in amount and consistency; effective regeneration

muscle tissue

A body tissue that contracts or shortens, making body parts move

muscle tissue

irritable; contractile; elastic

neural tissue

carries electrical signals from one part of the body to another

neural tissue

irritable; conductive; long, drawn out cytoplasms; supported by neuroglia

endocrine

secreting internally

exocrine

gland that secretes its products through excretory ducts to the surface of an organ or tissue or into a vessel
