ANATOMY

Detailed explanation-1: -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-2: -The ureters are two tubes that drain urine from the kidneys to the bladder. Each ureter is a muscular tube that drains into the bladder. Smooth muscle contractions in the walls of the ureters, over time, send the urine in small spurts into the bladder, the organ where urine is stored before it can be eliminated.

Detailed explanation-3: -In turn, the major calyces join to form the funnel-shaped renal pelvis. * The renal pelvis collects urine from the calyces and transports it to the ureter.

Detailed explanation-4: -Urine is essentially water, ions, and secreted molecules that leave the collecting duct of the many nephrons of the kidney and flow into the ureters. The ureters are two tubes that drain urine from the kidneys to the bladder. Each ureter is a muscular tube that drains into the bladder.

Detailed explanation-5: -The ureters use smooth muscle contractions to facilitate the flow of urine. The urinary bladder is a hollow, muscular, and elastic organ that stores urine.
