Killer whales are marine mammals belonging to the family Delphinidae, formed by several species of dolphins, false killer whales and pilot whales.
Active transport is the key to the reabsorptive processes in the proximal tubule. Glucose and amino acids are reabsorbed across the apical membrane of the proximal tubule by sodium-coupled secondary active transport. Na + glucose transport is mediated by the low affinity, high capacity SGLUT2 transport protein.
As with the proximal tubule, the processes of both reabsorption and secretion continue in the loop of Henle. As shown in the table above, approximately 2/3 of the water in your urine is reabsorbed in the proximal tube. Almost all the rest of it is reabsorbed in the loop of Henle.
