Which process in the mammalian nephron is generally considered the least selective, allowing most plasma solutes except proteins and cells to pass from blood into the nephron tubule?

  • A: Filtration
  • B: Reabsorption
  • C: Active Transport
  • D: Secretion

Explanation

Glomerular filtration is the least selective process in the nephron. It is a bulk flow process where most components of the blood plasma, except large proteins and blood cells, are forced into Bowman's capsule to form the filtrate. Subsequent processes like reabsorption and secretion are highly selective.
