Many systems of the Komodo Dragon such a circulatory, respiratory, and nervous, all work together to make up a central function. This way, the komodo can live, eat, and do whatever komodo dragons do. If all of these systems could not tie together, the komodo would be basically useless. See diagrams below.
This diagram shows the various systems of the Komodo Dragon, and how they work together to preform one specific function, to let the komodo dragon live. The respiratory system allows blood to flow through the Komodo. This works in tandem with the respiratory system, witch delivers oxygen to the blood. The blood then flows to the brain and delivers supplies that lets the brain live.
