Organs in the excretory system rid the body of metabolic waste products and pollutants. This includes the elimination of urea from circulation and other bodily wastes in humans. While solid wastes are eliminated from the large intestine, urea elimination takes place in the kidneys.
How do the kidneys work?
- The body transforms nutrients from meals into energy. Waste products are left in the blood and bowel after the body has utilized all the required nutrients from meals.
- The waste products are expelled with the aid of the urinary system and kidneys. They also maintain the proper balance of water and substances like potassium and salt. The body's hazardous waste products from food metabolism are filtered by the kidneys and removed. If these waste products accumulate in the body, it may lead to issues. The body's fluid and acid-base balance are both regulated by the kidneys.
- The kidneys are two bean-shaped organs. They are located below the ribs toward the middle of the back.
- Through microscopic filtering organs called nephrons, the kidneys eliminate waste substances from the blood called urea. Each kidney has roughly a million nephrons. A glomerulus, a ball of tiny blood capillaries, and a renal tubule, a tiny tube, make up each nephron. The glomerulus receives blood and filters it there. The water and other materials are added to or subtracted from the filtered fluid as it travels through the tubule. Urine is the liquid that is left over.
- After the urine is created, it flows through the kidney's nephrons and down its renal tubules. The renal pelvis receives urine from the calyces, which then directs it into the ureter. It then descends and enters the bladder from here.
- The kidneys perform a number of essential tasks, including filtering waste from the blood and assisting with the body's fluid and other material balance.
