The importance of an element in the body is not solely related to its percentage of body weight. The evidence in the table supports this explanation. For example, even though iron has a very low percentage of body weight (0.006), it plays a crucial role in carrying oxygen in the blood, which is essential for human survival. On the other hand, elements like magnesium and phosphorus have higher
percentages of body weight (0.05 and 1.0, respectively) but are equally important for bone formation, muscle function, and teeth structure.

How much of an element is in your body doesn't always show how important it is. The table proves this.

- Iron is only 0.006% of your body, but it helps carry oxygen in your blood, which you need to live.
- Magnesium (0.05%) and phosphorus (1.0%) are found in larger amounts, and they help build bones, move muscles, and keep teeth strong.

So even very small amounts of some elements can be very important.
