Which one of the following correctly explains the function of a specific part of the human nephron?

Correct answer: A. Podocytes : create minute spaces (slit pores) for the filtration of blood into the Bowman's capsule

  • A. Podocytes : create minute spaces (slit pores) for the filtration of blood into the Bowman's capsule
  • B. Henle's loop : most reabsorption of the major substances from the glomerular filtrate
  • C. Distal convoluted tubule : reabsorption of K + ions into the surrounding blood capillaries
  • D. Afferent arteriole : carries the blood away from the glomerulus towards renal vein.

Explanation

The visceral layer of Bowman's capsule surrounds the glomerulus and is composed of special type of cells, the podocytes. The podocytes are so called because they possess foot like processes (projection), the pedicels. The space between pedicels are called slit pores (= filtration slits) through which the glomerular filtrate filters.

About Homeostasis

Homeostasis maintains a stable internal environment through the kidney and urinary system, thermoregulation and excretion. The kidney topics include filtration, selective reabsorption, urine formation and water balance, while thermoregulation involves sweating, vasodilation, vasoconstriction and hormonal control; excretion is different from egestion, which removes undigested food.
