The correct answer is iron, because it is often not included in children's multivitamin/mineral supplements. Iron is an important element for our health. It is especially important for the proper functioning of our red blood cells and it is found in many foods. Although iron is essential, too much can lead to iron toxicity. Iron poisoning was the leading cause of death from the medicine overdose in children younger than 6 years until the ends of the 1990s. But the trend has since changed due to better warning labels, education of prescribers, changes in iron preparations, and consumer awareness.

Explanation:
Functionally, the respiratory system is separated into a conducting zone and respiratory zone:
Conducting zone consists of the nose, pharynx, larynx, trachea, bronchi, and bronchioles. These structures form a continuous passageway for air to move in and out of the lungs.
Respiratory zone is found deep inside the lungs and is made up of the respiratory bronchioles, alveolar ducts, and alveoli. These thin-walled structures allow inhaled oxygen (O2) to diffuse into the lung capillaries in exchange for carbon dioxide (CO2).
The respiratory zone begins where the terminal bronchioles join a respiratory bronchiole, the smallest type of bronchiole, which then leads to an alveolar duct, opening into a cluster of alveoli.
