How is iron lost from the human body?
Question
How is iron lost from the human body?
Solution
Iron is lost from the human body through several mechanisms:
-
Shedding of Cells: The body continuously sheds cells from the skin, gastrointestinal tract, and urinary tract. These cells contain iron, which is lost when the cells are sloughed off.
-
Menstruation: In females, a significant amount of iron is lost during menstruation. The blood lost during the menstrual cycle contains iron, which is not recovered by the body.
-
Sweat: A small amount of iron is lost through sweat. Although this is a minor route compared to others, it still contributes to the overall iron loss.
-
Blood Loss: Any form of blood loss, such as from injuries, surgeries, or gastrointestinal bleeding, results in the loss of iron. Blood contains hemoglobin, which is rich in iron.
-
Excretion: Trace amounts of iron are lost through urine and feces. This is a minimal amount but still part of the overall iron loss process.
These mechanisms collectively contribute to the daily loss of iron from the body, necessitating the need for regular dietary intake to maintain adequate iron levels.

Two Kinds of IronThe human body needs iron to produce hemoglobin, a substance that helps red blood cells transport oxygen. Without enough iron, a person may feel tired and weak. Dietary sources of iron include plant sources, such as vegetables and beans, and animal foods, including poultry, red meat, and fish. However, plant and animal sources are not equal. The iron in plants, called nonheme iron, is not easily absorbed by the human digestive system. For example, a half cup of cooked spinach contains a healthy dose of over three milligrams of iron. Unfortunately, only five percent of that iron can be used by the body. On the other hand, the iron in animal foods, called heme iron, is better utilized. Heme iron is contained within a ring of protein, which helps the body to absorb it easily.What is the main, or central, idea of the passage?Plant and animal food sources both contain iron, which helps red blood cells carry oxygen throughout the body.Plant and animal food sources both contain iron, but the iron in animal foods is more accessible to the body.Heme iron, found in meat and fish, is easily absorbed by the human body.Submit
