Describe the path of urine from the kidney to the outside. Make sure your explanation includes all structures and muscles that are encountered as urine leaves the body
What will be an ideal response?
Urine forms in the nephrons, which then drain into the renal pelvis, out to the ureters, and eventually to the urinary bladder. Urine amounts build up to 200 milliliters in the urinary bladder; then the detrusor muscle contracts. This causes the internal urethral sphincter to relax, releasing urine into the urethra. About this time, a person feels the urge to urinate. The external urethral sphincter relaxes in order to release urine from the body.
