My buddy did not want to work on Saturday, but he complained to the plant manager instead of our department supervisor, completely ignoring the organizational structure of our company. 5 people found this helpful.
Air can also be taken in through the mouth. These two openings of the airway (the nasal cavity and the mouth) meet at the pharynx, or throat, at the back of the nose and mouth. The pharynx is part of the digestive system as well as the respiratory system because it carries both food and air. At the bottom of the pharynx, this pathway divides in two, one for food (the esophagus, which leads to the stomach) and the other for air.
The organs of the respiratory system make sure that oxygen enters our bodies and carbon dioxide leaves our bodies. The respiratory tract is the path of air from the nose to the lungs. It is divided into two sections: Upper Respiratory. Tract and the Lower Respiratory Tract. Included in the upper respiratory tract are the Nostrils, Nasal Cavities, Pharynx, Epiglottis, and the Larynx. The lower respiratory tract consists of the Trachea, Bronchi, Bronchioles, and the Lungs. As air moves along the respiratory tract it is warmed, moistened and filtered. The lungs flank the heart and great vessels in the chest cavity.
