Question 35 (7 points) The kidneys are the third line of defence in pH regulation. The diagram of the nephron below has seven boxes labelled with an arrow and a letter. If a person was suffering from acidosis, indicate the response of the nephron by stating which ion would be the most appropriate for each of the arrow/letters. An T indicates the predicted increase in the movement of anion; a 4 indicates a predicted decrease in the movement of anion. The large arrows (outside the boxes) indicate the direction of movement of the filtrate. The renal tubule and peritubular capillary are labelled. Peritubular capillary Renal - Tb tubule sy i _-~ Ve Te Ta ve Match the letters in the figure above to the ion movements listed below.
