If a person eats 12 milligrams (mg) of salt in a day and excretes 11 mg of it in the urine, what happened to the remaining 1 mg?
To determine: The fate of 1 milligram of urine if a person’s intake of salt is 12 milligram and excretion of salt is 11 milligram.
Introduction: Excretion can be defined as the removal of waste material or substances from the body generally by means of feces, urine, skin, or lungs. The main organ for the removal of waste material from the body is the kidney.
Explanation of Solution
When a person consumes 12 milligrams of salt and excretes 11 milligrams of salt by excretion process, the remaining 1 milligram of salt will retain inside the body of that person. This remaining amount of salt will metabolize into a new type of substance.
Therefore, 1 milligram of the salt will retain inside the body of the living organism if it intakes 12 milligrams of salt and excretes 11 milligrams of salt.
