Exploring the Role and Function of the Kidneys

Regulating water balance

In an average adult, water will make up approximately 60% of the body weight. Your body must contain the appropriate amount of water to maintain a healthy balance.  When blood is filtered in the kidneys, it is able to monitor and balance the water levels by preserving what the body needs. This allows our body to avoid dehydration while removing excess water and electrolytes in the form of urine.
