Sheets of tissue that cover the external surface of the body, line tubes or passages leading to exterior, line internal cavities in the body. Little intercellular substance (intercellular is the stuff between cells) Has free surface and rests on some connective tissue. Forms the epidermis, (the outer skin layer) and internal membranes continuous with the skin. (e. g. mucous membranes) Some epithelial cells are in the shape of a column and have cilia, and are in the eyes and ears: endothelial tissue. Inner lining of walls of blood and other vessels; not continuous with the skin. Cells have flat smooth shape to avoid blood clotting: mesothelial. Lines primary body cavities (e. g. pleuaral cavities) Connect or bind structures together, support/maintain the body. Fewer cells with ore intercellular matric (more space in between) Intercellular matrix (nonliving) characterized type of connective tissue. Found many places in the body, job is to bind parts together and allow movement.
