The kidney is the part of the human body where the blood is purified. The kidney is in charge of cleansing the blood. Two bean-shaped organs, the kidneys are each roughly the size of a fist. One kidney is situated on either side of your spine, directly below the rib cage.

Blood Purifier of the Human Body

  • Every minute, healthy kidneys filter around a half cup of blood.
  • The kidney also eliminates surplus fluid and waste, excreting it from the body in the form of urine.
  • The kidneys also eliminate acid that the body's cells create and keep the blood's levels of water, salts, and minerals including sodium, calcium, phosphorus, and potassium in a healthy range.
  • The kidney also aids in the production of hormones that maintain bone strength, regulate blood pressure, and create red blood cells.
  • Every part of the body receives oxygenated blood from the heart.
  • Through two tiny channels, the gall bladder stores the urine and sends it to the ureters.
  • Bile produced by the liver is also kept in the gallbladder.
  • Food digestion is aided by the somewhat alkaline composition of bile juice.

Function of the kidney

  • The kidney's primary job is to filter blood so that urine can be produced.
  • It excretes metabolic wastes into the urine, including urea and uric acid.
  • It releases several hormones and enzymes, including:
    • The release of erythropoietin in response to hypoxia
    • Renin: Aldosterone and Ang II are regulated to lower blood pressure.
    • Calcitriol: It facilitates calcium absorption in the intestines.
  • By reabsorbing bicarbonate from urine and excreting hydrogen ions and acid ions into the urine, it keeps the body's acid-base balance in check.
  • By cooperating with the pituitary gland, it also keeps the body's salt and water levels stable.

Summary:

In which part of the human body is the blood purified? (a) Heart (b) Kidney (c) Lungs (d) Intestine

The human body's kidneys are where the blood gets cleaned. Blood purification is the responsibility of the kidney. The kidneys are two bean-shaped organs that are each around the size of a fist. On either side of your spine, just below the ribs, is one kidney.
