Hint: Two bean-shaped organs, each about the size of a fist, make up the kidneys. One on either side of the spine is found just below the rib cage. Per minute, healthy kidneys pump around a half cup of blood, extracting wastes and excess water.
Complete answer:
Kidneys are reddish brown bean-shaped structures located close to the dorsal inner wall of the abdominal cavity between the stages of the last thoracic and third lumbar vertebra. Urine is formed when the kidneys extract wastes and excess water from the blood. On average, an adult person excretes 1 to 1.5 litres of urine every day. The urine produced is a light yellow coloured watery fluid with a characteristic odour. It is mildly acidic (pH-6.0).
The renal artery transports waste products to the kidneys. Blood is transferred to 1.2 million filtering units called nephrons for each kidney. Nephron cells take in the blood's liquid component and flush out impurities (urea, mineral salts, and other toxins). The renal vein returns necessary substances to the bloodstream, such as salts, water, glucose (sugar), and other nutrients.
Urine is the waste-containing fluid that remains in the nephrons. The waste products are dissolved in urine, which is 95 percent water. Urine is carried from the kidneys to the urinary bladder through ureters, a pair of tubes. Urine is emptied from the bladder into the urethra, a duct leading outside the body.
Hence, Kidneys eliminate the waste materials in the liquid form called Urine.
Note: If we are urinating more often, particularly at night, it may be a sign of kidney disease. When the kidney filters are weakened, the urge to urinate may become stronger. In men, this may often be a symptom of a urinary infection or an enlarged prostate.
