Basic Anatomy of the Human Genitourinary Tract

The urinary system's function is to filter blood and create urine as a waste by-product. Organs of the urinary system include kidneys, renal pelvis, ureters, bladder and urethra.

Upon examination specific "landmarks" are used to describe the location of any irregularities in the bladder.

These are:

• trigone: a triangle-shaped region near the junction of the urethra and the bladder
• right and left lateral walls: walls on either side of thetrigone
• posterior wall: back wall
• dome: roof of the bladder
