This module on the genitourinary system is one of 17 modules designed for individualized instruction in health occupations education programs at both the secondary and postsecondary levels. It is part of an eight-unit miniseries on anatomy and physiology within the series of 17 modules. Following a preface which explains to the student how to use the module, the unit consists of a pretest with answers, three sections (information sheets) with their objectives (e.g., identify and describe the location and anatomical structure of the kidneys), optional activities (e.g., research the process of dialysis by an artificial kidney machine), and posttests, and a glossary of terms. Topics covered in the unit are introduction to the genitourinary system, the urinary system, and the male reproductive system. An accompanying instructor's guide contains suggestions for using the module and answers to the posttest. (KC)
