Solution

The correct option is B Nephron
  • Nephron is the structural and functional unit of the kidney.
  • Its chief function is to regulate the concentration of water and soluble substances like sodium salts by filtering the blood, reabsorbing what is needed and excreting the rest as urine.
  • Each nephron is composed of two main structures: the glomerulus and renal (kidney) tubule. There are about 1,000,000 nephrons in each human kidney.
Therefore, the correct answer is option B.
