Circulatory system

u owe this ropey motherfucker everything. concept is to circulate a fluid between the tissue and our lungs (won’t get into that but i’m sure we’ll get to respiratory system as well my lovelies), how to we do that? let’s place a massive fuckoff engine in the middle, with two prechambers and two main chambers and split it down the middle. connecting the chambers and the main artery are valves, which close in different phases due to electric stimulation. so they shoot the blood forth through the system, picking exchanging o2 and co2 through diffusion, where gases want to go where there is a lesser concentration of it, and picking up new oxygen in the alveoli. oh and it’s divided into two, the big/system circuit and the small/pulmonary/lung system.
