Detailed explanation-1: -The kidneys filter all the blood in the body many times each day and produce a total of about 1.5 pints of urine. The amount of water lost in urine is controlled by the kidneys. The kidney is the structural and functional unit of the nephron. Excretion is one of the major ways the body maintains homeostasis.
Detailed explanation-2: -The kidneys filter that blood about 40 times a day! More than 1 million tiny filters inside the kidneys remove the waste.
Detailed explanation-3: -Each kidney weighs about 160 grams and gets rid of between one and one-and-a-half litres of urine per day. The two kidneys together filter 200 litres of fluid every 24 hours.
Detailed explanation-4: -The urinary system’s function is to filter blood and create urine as a waste by-product. The organs of the urinary system include the kidneys, renal pelvis, ureters, bladder and urethra. The body takes nutrients from food and converts them to energy.
Detailed explanation-5: -Here’s how kidneys perform their important work: Blood enters the kidneys through an artery from the heart. Blood is cleaned by passing through millions of tiny blood filters. Waste material passes through the ureter and is stored in the bladder as urine. Newly cleaned blood returns to the bloodstream by way of veins.
