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.
This exchange process occurs in the alveolar region of the lungs. The respiratory system can be subdivided into an upper respiratory tract and a lower respiratory tract based on anatomical features.The upper respiratory tract includes the nasal passages, pharynx and the larynx, while the lower respiratory tract is comprised of the trachea, the primary bronchi and lungs.his exchange process occurs in the alveolar region of the lungs.
