What is the primary mechanism by which the kidneys regulate acid-base balance?

Step 1: Understand that the body needs to maintain a balance between acids and bases to function properly.
Step 2: Know that the kidneys are organs that help control this balance.
Step 3: Learn that the kidneys can remove excess hydrogen ions (which are acidic) from the blood.
Step 4: Recognize that the kidneys also reabsorb bicarbonate (which is basic) back into the blood.
Step 5: Realize that by excreting hydrogen ions and reabsorbing bicarbonate, the kidneys help keep the blood's pH level stable.
