As a result, gas carriage around the body is essential to organisms. There are two main sections to gas carriage - the carriage of oxygen and the carriage of carbon dioxide. Although the two gases can be carried using entirely different methods, they work together to keep constant gradients for efficient transport. Oxygen needs to be transported from the lungs to all parts of the body as all respiring tissues need it (C6H12O6 + 6O2 --> 6CO2 + 6H2O).
