An advantage of the gas exchange system in mice is that they have a circulatory system. Oxygen which is absorbed by the blood is transported to every cell in the mouse's body through their bloodstream. Simply put this means that no matter the size of the mouse, each and every cell will have a capillary delivery oxygen to it. Another example of a mouse’s gas exchange system is the large surface area to volume ratio. The alveoli uses the most of the surface area that they possibly can, which allows more oxygen to be diffuses at any one time, which in turn increases the effectiveness of the mice gas exchange system. this is an important advantage of the mice gas exchange system as it allows the mouse to get plenty of oxygen to their cells for
