Urinary System

In this lab you will learn about a number of urinary system structures.

Begin by clicking on the following:

    Anterior urinary system

Here you will see the entire urinary system. Locate the following:

    Kidneys right and left

    Renal pelvis right and left

    Ureters right and left

    Detrusor of the urinary bladder

    External urethral sphincter

    Muscular layer of the male urethra

Dissect away the detrusor of the urinary bladder. The detrusor muscle is a smooth muscle that contracts when you void. The inner portion of the bladder consists of transitional epithelium.

    Anterior urinary system with prostate

This view shows the male urinary system with the prostate gland. Locate the prostate. Although the prostate is primarily a part of the male reproductive system the urethra moves through it.

Males sometimes suffer from a condition of the prostate called benign prostatic hyperplasia or BPH. In BPH the prostate gland enlarges and sometimes blocks the urethra resulting in difficulty urinating.

Use your text to locate the other urinary structures on your list.

This concludes the lab.
