The Respiratory system

Structures of the Respiratory system

Upper respiratory- includes the nose, mouth, and the beginning of the trachea
Lower respiratory- includes trachea, the bronchi, broncheoli and the lungs

How it relates to immunity

Mucus, produced by specialized cells lining the airway walls, is sticky and traps a great deal of the inhaled dust, pollen, bacteria, and viruses.

The body's use of nutrients

According to the American Lung Association, carbohydrates produce more carbon dioxide than protein or fat. Therefore, a diet high in carbohydrates puts more stress on the respiratory system by requiring the lungs to release an abundance of carbon dioxide.
