The human body converts nutrients from food into energy. Waste products are left after the body has received the food components it requires. The kidney and urinary systems aid in the elimination of urea, a type of liquid waste. When protein-rich foods (meat, poultry, and certain vegetables) are broken down in the body, urea is formed. They also aid in balancing water, potassium, and sodium levels, among others. Urea goes to the kidneys as it is carried by the blood. There, along with other wastes, it is being removed from the body. The urinary system includes the kidney, ureter, bladder, sphincter muscles, and urethra.
Bladder – A hollow organ found in the lower belly. It has the ability to expand to store urine and contract to empty urine through the urethra. It also has nerves that alert a person when it is time to urinate.
Ureter – Tubes that carry urine from the kidneys to the bladder. As its muscles tighten, it forces urine to go downward, or away from the kidneys. Urine is being emptied into the bladder from the ureter every 10 to 15 seconds.
Renal pelvis – It is located in the central region of the kidney, and it collects urine as it is being produced.
