Hint: The human excretory system is mainly responsible for the elimination of metabolic wastes and toxic materials from the body that are produced by homeostasis and helps to maintain the pH of body fluids. There are several parts of the body that are involved in the process of excreting specific metabolic wastes, such as sweat glands, the liver, the lungs and the most important excretory organs are the kidneys, ureter and urinary bladder.

Complete answer:
-Characteristic Functions of Kidney:
All humans possess two kidneys. The kidneys are large, two bean-shaped organs which are located in the abdominal cavity on either side of the vertebral column. Each kidney is supplied with blood from the renal artery and the function of each kidney is to filter the blood from toxic wastes such as urea, salts as well as excess amounts of water. The toxins as well as the waste fluids which are filtered from the blood gets excreted through Urethra in the form of urine. Each kidney consists of three sections namely, the renal cortex, the renal medulla and the renal pelvis.
-Prominent Functions of Ureter:
The ureters are the tubes of muscular ducts that transmits urine from the kidneys to pass through the urinary bladder. Muscles in the walls of the ureter get tightened and relaxed in order to force the flow of urine downward and away from the kidneys.
-Significant Functions of Urinary bladder:
Urinary bladder is a triangle-shaped, hollow organ which is present in the lower abdomen of the body. It collects the waste fluids and toxins excreted by the kidneys in the form of urine. It is generally considered as the temporary storage reservoir as it stores urine until it gets excreted out via the urethra.

Note: The formation of hard deposits or solid masses made of crystals that consists of minerals and salts in kidneys are known as kidney stones. This condition is also referred to as renal calculi and one of the best ways to prevent this condition is to drink enough water or fluids every day.
