Human And Bluefin Tuna Respiratory System

When comparing the human and Bluefin tuna respiratory system, it is evident that tunas require a more efficient process as they obtain their oxygen from water, which is denser than air. With that being said, the tunas need movement to force the water over their gills, whereas humans rely on the contraction of the internal muscles which changes the pressure inside the lungs taking air in and out. The position of the respiratory organs also differ in the two, with humans respiratory organs located in the upper torso and the bluefin tunas on either sides of their bodies. Another difference between the two is their main respiratory organs. For humans its the lungs which assist in the absorption of the air that humans breathe. In the Bluefin tuna
