Genitourinary System (Anatomy)

This session will introduce you to the anatomy of the genitourinary system. A pre-recorded lecture is provided for you to introduce the learning objectives and direct you through these. You will need to explore the additional recommended resources to assist in your learning. The urinary and genital (or reproductive) systems may be considered together since they are closely linked. The similarities and differences of the male and female genitourinary systems will be explored and emphasis will be placed on the functional anatomy of the different structures therein.
