epithelial cells that produce secretions

individual gland cells scattered among other cell types in an epithelium

where most or all of the epithelial cells produce secretions

epithelial cells that lack a free surface

atoms combine to form molecules and molecules interact to form cells

cells secrete and regulate extracellular material and fluids and cells combine to form tissues

tissues with specialized functions combine to form epithelial tissue, connective tissue,muscle tissue, and neural tissue; these form organs

covers exposed surfaces; lines internal passageways and chambers; produces glandular secretions

fills internal spaces; provides structural support; stores energy

contracts to produce active movement

conducts electrical impulses; carries information
