ANATOMY

Detailed explanation-1: -Ureters: These two thin tubes inside your pelvis carry urine from your kidneys to your bladder. Bladder: Your bladder holds urine until you’re ready to empty it (pee). It’s hollow, made of muscle, and shaped like a balloon.

Detailed explanation-2: -The sphincter is a muscle around the opening of the bladder. It squeezes to prevent urine from leaking into the urethra. This is the tube that urine passes through from your bladder to the outside. The bladder wall muscle relaxes so the bladder can expand and hold urine.

Detailed explanation-3: -The muscles of your bladder wall remain relaxed while the bladder fills with urine, and the sphincter muscles remain contracted to keep urine in the bladder.

Detailed explanation-4: -Urine is made in the renal tubules and collects in the renal pelvis of each kidney. The urine flows from the kidneys through the ureters to the bladder. The urine is stored in the bladder until it leaves the body through the urethra.

Detailed explanation-5: -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.
