The process diagram shows that box A represents the kidneys. The arrow pointing towards box A indicates that the kidneys are receiving blood. The arrow pointing away from box A indicates that the kidneys are producing urine. The pH scale on the diagram shows that a pH of 7 is neutral, below 7 is acidic, and above 7 is basic. The arrow pointing towards the pH scale shows that the blood pH is too basic (above 7), and the arrow pointing towards box A shows that the kidneys are receiving this basic blood. Therefore, in order to correct the blood pH, the kidneys need to excrete urine that is more acidic, resulting in a change in box A.
