Detailed explanation-1: -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-2: -The urine travels from the kidneys to the bladder in two thin tubes called ureters. The ureters are about 8 to 10 inches long. Muscles in the ureter walls tighten and relax to force urine down and away from the kidneys. Small amounts of urine flow from the ureters into the bladder about every 10 to 15 seconds.

Detailed explanation-3: -Urethra. This tube allows urine to pass outside the body. The brain signals the bladder muscles to tighten, which squeezes urine out of the bladder. At the same time, the brain signals the sphincter muscles to relax to let urine exit the bladder through the urethra.

Detailed explanation-4: -Urine flows through a renal pyramid and exits at the renal papilla, the tip. The renal papilla has collecting ducts, small openings that allow urine to pass through. From the collecting ducts, the urine progresses to the renal pelvis, a widened area of the kidney, and exits through the ureter.

Detailed explanation-5: -The ureter is a small tube, or duct, that connects the bladder and kidneys. Urine passes through the ureter from the kidneys to the bladder. The urethra is the tubular path that connects the bladder to the body’s exterior, allowing urine to exit the body.
