Final answer:
The body loses some iron daily via urination, respiration, fecal excretion, and blood loss.
Step-by-step explanation:
The body loses some iron daily via urination, respiration, fecal excretion, and blood loss. Urine, bile, feces, cellular desquamation, and sweat are the normal routes of iron excretion. In an adult male, daily excretion is estimated to be about 1 mg. Additional loss through menstruation averages to 1 mg per day in women of reproductive age.
