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.
Well, these are two completely different systems. The Respiratory system is the system of your body that deals with the exchanges of gases in your body, such as oxygen and carbon dioxide (waste from your cells). The Circulatory system deals with circulating blood throughout your body. However, even though these are two different systems, they are vital to each other. Your heart (Circulatory) and your lungs (Respiratory) are vital to each other. The blood in your body needs oxygen to produce energy in your body. The only way to obtain such is through the Respiratory system.
