In place of the heart and lungs of a human is a Machina's Core. The Core is responsible for supplying the Machina's body with useful materials and power. Anything the Machina eats, drinks, or breathes-in travels to the first part of the Core; the Matter-Shredders, located in the top spaces of her chest cavity. M2 Nanomachines and Machinium are immediately filtered out and enter the Machina's bloodstream. Next, matter is separated into free molecules. Useful molecules and atoms are again diverted into the bloodstream. Anything not deemed useful at the end of this process enters the Mass-Reactor in the center of the chest cavity. There, matter is converted almost 1:1 into energy to power the Machina's body. Leftover subatomic particles are taken to smaller organs attached to the Mass-Reactor where they can be fused together to make atoms and molecules the Machina needs but cannot find elsewhere. Due to the extremely complex mathematics involved in these reactions, a [https://wiki.machinamaincluster.com/index.php/M2-Based_Life-Forms#Larvae Larva] is needed for the Core to operate at full output. This Core Larva monitors all the Core's processes and performs the unfathomable calculations necessary to maintain the reactions in the Core.

In the lower areas of the chest cavity attached to the Core assembly are the pumps for the Machina's circulatory system. The organs there pump the Machina's blood around her body and monitor the raw materials in the blood to ensure supply from the Core is sufficient. Incoming blood goes through the pumps, collects power and materials from the Core, then travels around the body before returning. Notably, the circulation systems do not feature a heartbeat. As the pump organs develop around the human heart, the heart will stop beating, which can be significant moment in a Machina's early [https://wiki.machinamaincluster.com/index.php/Machina_Development#Category_1 development].

Due to how the Core only requires matter for fuel, any matter will do for survival. However, Machina retain the ability to fully appreciate human food with far greater sensory definition. In addition, because most metals are nutritious for Machina, their bodies also interpret these metals to be tasty. As a result, both human food and most metals have appreciable tastes for a Machina.
