Verified step by step guidance

Step 1: Understand the primary function of the kidneys. The kidneys are vital organs responsible for filtering blood, removing waste products, and maintaining homeostasis in the body.

Step 2: Focus on the regulation of water content and electrolytes. The kidneys play a key role in balancing electrolytes such as sodium (Na⁺), potassium (K⁺), and chloride (Cl⁻), which are essential for nerve function, muscle contraction, and maintaining fluid balance.

Step 3: Eliminate options that are not directly regulated by the kidneys. For example, oxygen saturation is primarily controlled by the respiratory system and hemoglobin in the blood, not the kidneys.

Step 4: Consider blood glucose levels. While the kidneys can reabsorb glucose during filtration, they do not actively regulate blood glucose levels; this is primarily managed by the pancreas and hormones like insulin.

Step 5: Evaluate body temperature. Body temperature is regulated by the hypothalamus and mechanisms like sweating and shivering, not the kidneys. Therefore, the correct answer is electrolyte balance.
