In the living organism, energy is liberated, along with carbon dioxide, through the oxidation of molecules containing carbon. Pyaemic pneumonia - Multiple small abscesses scattered through the lungs that have been carried there via the blood stream. Both organisms get oxygen by breathing through the nose and then having the oxygen transferred by the trachea to the lungs. They warm and filter air as it passes through the nose. Another interesting fact is that coelacanths give live birth, something else thats very odd for a fish to do. They are responsible for providing the blood circulatory system with oxygen, which will then be transported to all other organs in the body, and also helping remove carbon dioxide from the bloodstream. Gene expression in upper respiratory system is categorized based on two gene classification strategies, tissue detection and tissue specificity. The main role of the respiratory system is to capture oxygen from the air as well as to eliminate CO2 from tissue catabolism. This unique advancement makes it so that elephants can snorkel in relatively deep water, an ability that is also aided by the elephants unusually long nose, also known as a trunk.
