After an introductory segment on cell characteristics, this program discusses the way human body cells function and combine into the structures that sustain life. Topics include membrane permeability and the processes of passive and active transport; cytoplasm, with its cytosol, organelles, and inclusions; the constituent parts of the nucleus and the stages and processes of the cell cycle; the four basic tissue types; and the skin, the body's largest organ.
