Explanation: 

Detailed explanation-1: -Waste products and urine move through your ureters to your bladder. Your bladder stores urine until you use the toilet. Urine leaves your body through your urethra.

Detailed explanation-2: -Bladder. A hollow, muscular, balloon-shaped organ that expands as it fills with urine. The bladder sits in your pelvis between your hip bones. A normal bladder acts like a reservoir.

Detailed explanation-3: -Bladder. This triangle-shaped, hollow organ is located in the lower abdomen. It is held in place by ligaments that are attached to other organs and the pelvic bones. The bladder’s walls relax and expand to store urine, and contract and flatten to empty urine through the urethra.

Detailed explanation-4: -The main excretory organ of the human body is kidneys. There are one pair of kidneys which filter blood and remove waste products in the form of urine.

Detailed explanation-5: -After urine forms in the kidneys, it is transported through the ureters (one per kidney) to the sac-like bladder, which stores the urine until urination. During urination, the urine is released from the bladder and transported by the urethra to be excreted outside the body through the external urethral opening.
