as we all know that the structural and functional unit of kidney are nephrons. all the nephron opens into the collecting tubes which opens into the collecting duct which further leads to the pelvic when urine passes through the pelvic into the ureter which takes it to the urinary bladder and leaves the bladder during micturition (urination) via a memberanous duct called urethra. the urine is stored into the bladder until it's extended pressure leads to the urge the urine. the bladder is a muscular sac like structure under the nervous control that's why we usually urge to urinate.

Answer:
The wastes that are produced in human body are removed by the process of excretion. Human body consists of a number of excretory organs such as liver, skin, kidneys etc. But there is a specialized system in humans that helps to purifies blood. That is called excretory system. It consists of Kidneys, ureters, urethra, urinary bladder .
Kidneys are placed in lower abdomen and bean like shaped. They filter the blood and removes toxins from the blood. It also reabsorbs the essential ions and substances from the filtrate. The final toxins are collected and removed from the body in the from of urine.
The urine is 95% of water in composition and rest it contains urea and other wastes.
