Your body constitutes a system of organized units controlling your internal environment,such as the concentration of Na⁺ in your blood.If this concentration falls below normal,you would have hyponatremia,a condition that can cause headaches,mental confusion,and even seizures.Which event would most likely cause hyponatremia? A) Gut cells absorbing too much Na⁺ from food B) Kidney cells absorbing too much Na⁺ from urine C) Sweating profusely,followed by drinking large quantities of water D) Producing increased amounts of urine after drinking several cups of coffee E) Kidney cells excreting Na⁺ into the urine

When you sweat profusely and then drink large quantities of water, you dilute the concentration of Na⁺ in your blood, leading to hyponatremia. This is because when you sweat, you lose both water and electrolytes like Na⁺. If you then drink only water without replacing the lost electrolytes, the concentration of Na⁺ in your blood will decrease.
