Urine Transport, Storage, and Elimination

The urinary organs include the kidneys, ureters, bladder, and urethra.

The ureters are two tubes that drain urine from each of the kidneys into the bladder.

The urinary bladder is a hollow, muscular, and distendible or elastic organ that sits on the pelvic floor.

The urethra is a muscular tube that connects the bladder with the outside of the body and removes urine from the body.

Micturition is the ejection of urine from the urinary bladder through the urethra to the outside of the body.

In addition to the kidneys, the liver, skin, and lungs also have important roles in the excretion of waste from the body.
