This chapter shows how the cells of a multicellular animal share the work: cells form tissues, tissues build organs and organs team up as organ systems. It then studies one vertebrate in detail, the frog (Rana tigrina), system by system: its external form and its digestive, respiratory, circulatory, excretory, nervous, endocrine, sensory and reproductive organs. It sets up the human physiology chapters that follow.
