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]. | In the lower areas of the chest cavity attached to the Core assembly are the pumps for the Machina's circulatory system.
