Sites of filtration in nephron are:
Correct answer: A. Glomerulus and Bowman's Capsule
- A. Glomerulus and Bowman's Capsule
- B. Proximal and distal convoluted tubules
- C. Ascending and descending limbs of the loop of Henle
- D. Collecting duct
Explanation
Option A is correct.The correct answer is the Glomerulus and Bowman's Capsule. These structures are part of the renal corpuscle, which is the initial site of filtration in the nephron. The glomerulus acts as a sieve, filtering blood to produce a filtrate, which is collected by the Bowman's capsule. The proximal and distal convoluted tubules, as well as the loop of Henle, are involved in the reabsorption and secretion processes, not the initial filtration. Similarly, the collecting duct is involved in the final concentration of urine, not its filtration.

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.
