How do you trace flow of urine out from the kidney in males?

1. Renal pelvis: Urine produced in the kidneys collects in the renal pelvis, which is a funnel-shaped structure located at the upper part of each kidney.

2. Ureter: From the renal pelvis, urine flows into the ureter, a long, thin tube that carries urine from the kidney to the urinary bladder. In males, the ureters are approximately 25-30 cm long.

3. Urinary bladder: The ureters enter the urinary bladder, a muscular organ that stores urine until it is ready to be eliminated. In males, the urinary bladder is located in the lower abdomen, just above the pubic bone.

4. Urethra: When you need to urinate, the urinary bladder contracts and pushes urine out through the urethra, a tube that carries urine from the bladder to the outside of the body. In males, the urethra is approximately 15-20 cm long and passes through the penis.

Along this pathway, urine undergoes several modifications and is subject to various regulatory mechanisms that control the volume, composition, and flow of urine.
