multiple choice question
which organ maintains body water at a normal level?
gallbladder

Explanation:

The kidneys filter blood, reabsorb water and excrete waste. They regulate the body's fluid - electrolyte balance, maintaining body water at a normal level. The gallbladder stores and concentrates bile, the pancreas produces digestive enzymes and hormones, and the liver has functions like detoxification and metabolism of nutrients, but none of these organs primarily maintain body water levels like the kidneys.
