The structures of the human body are organized on six levels. Human body contains atoms held by chemical bonds. Metabolism: sum of all chemical reactions in body: obtaining and producing energy, making body structures. Responsiveness: ability to detect and respond to internal and external environments, to sense changes and react. Movement: motion of whole body, individual organs, single cells, intracellular structures. Respiration: obtaining oxygen; removing carbon dioxide; releasing energy from foods. Digestion: breakdown and delivery of nutrients. Absorption: passage of subtances through membranes and into body fluids. Assimilation: changing of absorbed substances into chemically different forms. Circulation: movement of substances i body fluids. Excretion: elimination of waste from metabolic reactions.
