GENERAL HISTOLOGY

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: -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-3: -The primary function of the detrusor muscle is to contract during urination to push the urine out of the bladder and into the urethra.

Detailed explanation-4: -Each kidney has a narrow tube called a ureter, which carries urine from the kidney to the bladder. Muscles in the ureter walls tighten and relax forcing urine down this tube, away from the kidneys.
