Answer:
Two substances which are selectively reabsorbed from the tubules of a nephron are Amino acids and Glucose.
Explanation:
The majority of the vital nutrients (which do not have to be discharged out) are recovered by the bloodstream out from tubule of the nephron all through re - absorption, a key procedure in urine production that primarily takes place in the PCT of the nephron. Proximal tubule includes unique cuboidal epithelial cells having microvilli towards the lumen for completing this. Higher substance reabsorption is a result of this. Because glucose and amino acids seem to be essential to the organism, hence the nephron's tubules reabsorb them. Moreover, sodium, water and other ions like sodium can also be reabsorbed by nephrons. Furthermore nephron tubules are in charge of waste product elimination and nutrient absorption.
