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 kidneys form the urine and account for the other functions attributed to the urinary system. The ureters carry the urine away from kidneys to the urinary bladder, which is a temporary reservoir for the urine. The urethra is a tubular structure that carries the urine from the urinary bladder to the outside.
Detailed explanation-3: -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-4: -The ureters work constantly, emptying urine into the bladder about every 10 to 15 seconds. In addition to their role in eliminating waste from the body, the kidneys also balance fluids in the body, release hormones to regulate blood pressure, and control the production of red blood cells.
