Gas Exchange
Oxygen is necessary in all living creatures. It is used as energy and supplied throughout the body using the organism's bloodstream. It provides as an energy source, and without it, life would not exist. Oxygen is not only used as a resource for breathing systems, but for metabolism as well. Oxygen is the base life element to all living things on Earth. Almost all living cells need oxygen in order to function.
The mitochondria, known as the power house organelle of the cell converts oxygen into energy. It absorbs almost ninety percent of oxygen that enters the body [1].

In humans, oxygen enters these organelles through the nasal cavity. It then passes through the larynx, trachea, then the bronchial tubes. These tubes are then lead into the lungs which are connected to the alveoli, and then diffused through capillaries into arterial blood [2]. This system that allows humans to breathe is called the respiratory system.
Once this has been preformed, mitochondria are then able to absorb the oxygen and control oxygen levels throughout the body. This entire process is known as cellular respiration. When oxygen is inhaled throughout the body, a waste product travels in the bloodstream as well called carbon dioxide. This organic compound has no use in our body, so it is expelled into the environment.
Cuttlefish and many other cephalopods breathe and obtain oxygen through their gills. They have three hearts, one for each set of gills. Their heart is able to pump the oxygen throughout their bloodstream. Oxygen is attained by the cuttlefish by allowing their mantle cavity to expand and water to flow in. The water is then entered into the siphon expelling water and proceeding in respiration, in which oxygen is spread throughout the cuttlefish. This efficient process is what allows cuttlefish to take in the most oxygen than any other mollusk.
