The human body is composed primarily of cells organized into four basic types of tissues: epithelial tissue, which covers surfaces and lines organs; connective tissue, including bone, blood, and fat; muscle tissue, which enables movement; and nervous tissue, which transmits signals. Epithelial tissues can be divided into simple epithelia with one or two cell layers and stratified epithelia with multiple cell layers, each with distinct cell shapes and functions.

Almost entirely composed of cells Can be divided into Simple and Stratified Epithelium Classified by the number of cell layers and the cell shape Home Simple Epithelium Stratified Epithelium
Consists of single-celled layers Main functions consist of absorption and filtration Has three primary shapes Home Simple Squamous Simple Cuboidal Simple Columnar Psuedostratified Columnar Courtesy of akay
Contain a sparse cytoplasm They consist of single flattened cells Specialize in diffusion and filtration Divided into two sections Home Simple Cuboidal Simple Columnar Psuedostratified Columnar Mesothelium Endothelium Courtesy of pbchua
Consists of a cube-like shape Contain one large spherical central nuclei Primary functions include secretion and absorption Home Simple Squamous Simple Columnar Psuedostratified Columnar
Creates a slick, friction reducing lining Found in hollow organs of cardiovascular system Allows the exchanges between blood streams and tissue cells Home Mesothelium Courtesy of Partlynch
Found in the serous membrane Lines the ventral cavity Covers organs Home Endothelium
Contains closely packed cells Located in areas of the digestive tract Associated mostly with absorption and secretion Home Simple Squamous Simple Cuboidal Psuedostratified Columnar Courtesy of Christis Photos
Looks as if many cell layers are present May or may not contain cilia and goblet cells Location depends on characteristics Home Simple Squamous Simple Cuboidal Simple Columnar Courtesy of Ra5my
Have two more cell layers Main concerns include protection Identified by apical layer Home Stratified Squamous Stratified Cuboidal Stratified Columnar Transitional
Most commonly found of all stratified epithelia Main functions include protection May or may not contain keratin Home Stratified Cuboidal Stratified Columnar Transitional
It is rare to find in the body Found in the ducts of larger glands Consists of only two layers Home Stratified Squamous Stratified Columnar Transitional
Not commonly found in the body It is located in smalls amounts in specific areas of the body Usually found in junctions of two other types of epithelium Home Stratified Squamous Stratified Cuboidal Transitional
They have the ability to alter their shape Basal cells are cuboidal or columnar Apical layer consists of domelike or squamous shaped cells Home Stratified Squamous Stratified Cuboidal Stratified Columnar
They are highly cellular Responsible for much of bodys movement Three different types Home Skeletal Muscle Cardiac Muscle Smooth Muscle
Attach to bones of the skeleton Forms the bodys flesh Allows the body to voluntarily create movement Home Cardiac Muscle Smooth Muscle
Found only in the walls of the heart Creates intercalated discs Aids in propelling blood throughout the entire body Home Skeletal Muscle Smooth Muscle
