Learning objectives

After completing this study unit you will be able to:

  1. Identify the organs that comprise the urinary system.
  2. Learn their position in the abdominal and pelvic cavities.

Watch videos

The urinary system is divided into two parts:

  • The upper part, that includes the kidneys and the ureters,
  • The lower part, that consists of the urinary bladder and the urethra.

The organs of the urinary system work together to remove excess fluid and other waste materials from the bloodstream, and also to store, transport and excrete urine from the body.

This video tutorial will introduce you to the main structures of the urinary system and their function in the body.

To improve your understanding of urinary system terminology, take a closer look at some commonly used roots, prefixes and suffixes in the video below which covers terminology of the urogenital system.
