Question

what is the primary site of filtration within the nephron?
answers: a - e
a loop of henle
b glomerulus
c distal convoluted tubule
d proximal convoluted tubule
e collecting duct

Explanation:

The nephron is the functional unit of the kidney. The glomerulus is a network of capillaries where blood is filtered. The loop of Henle is mainly involved in reabsorption and concentration of urine. The proximal and distal convoluted tubules are also for reabsorption and secretion. The collecting duct is for final urine concentration and transport. Filtration primarily occurs at the glomerulus.

Answer:

B. Glomerulus
