Nasal Cavity- it helps keep your nose moist by making mucus so you won't get nosebleeds from a dry nose. There are also little hairs that help filter the air you breathe in, blocking dirt and dust from getting into your lungs.
Pharynx- its primary functions is to warm and humidify air before it reaches the lungs.
Larynx- most basic function is to provide sphincteric protection of the lower airway, most efficiently achieved by simultaneous adduction of both vocal cords.
Bronchi - is a passage of airway in the respiratory tract that conducts air into the lungs.
Alveoli - where the lungs and the blood exchange oxygen and carbon dioxide during the process of breathing in and breathing out. Oxygen breathed in from the air passes through the alveoli and into the blood and travels to the tissues throughout the body.
