In our nose, the hair and mucus act as a filter and prevent dust and other harmful substances from entering the body through the nose by trapping them. C- shaped Cartilaginous rings provide structural support to the trachea and prevent it from collapsing. Alveoli are small air sacs in the lungs where gaseous exchange takes place. They are spread out all over the lungs so that it increases the surface area for the gaseous exchange. The diaphragm is a muscular sheet that's present beneath the chest cavity. It helps in the process of breathing.
