Solution:
  • Nephrons are found in the kidneys. So the answer is (D).
  • Nephrons are the functional units of the kidneys. They are responsible for filtering blood and removing waste products, including urea, creatinine, and excess water. Nephrons also help to regulate blood pressure and electrolyte levels.
  • Each kidney contains about 1 million nephrons. Nephrons are made up of two main parts: the glomerulus and the renal tubule.
  • The glomerulus is a network of capillaries that filters blood. The renal tubule is a long tube that reabsorbs water and other essential nutrients from the filtrate and secretes waste products into the filtrate.
