A Factory's Supply Chain Breaks Down

Imagine a factory (the liver) that relies on smooth highways (blood vessels with healthy endothelium) to receive raw materials and ship out products. The factory's supplier (the placenta) is supposed to send materials at a steady rate, but it's set up in a bad location (abnormal implantation) and can't deliver properly. In desperation, the supplier sends out toxic chemicals (sFlt-1 and soluble endoglin) that poison the highways — the smooth asphalt cracks, becomes sticky, and clots form everywhere (microthrombi). Delivery trucks (red blood cells) get shredded trying to squeeze through the damaged roads (hemolysis). The factory itself gets choked off from blood flow (hepatic starved blood flow (ischemia)), its workers (hepatocytes) die and spill their tools (AST/ALT) onto the ground, and the factory swells painfully inside its fence (Glisson capsule). The tollbooths (platelets) that normally collect fees smoothly get stuck trying to repair the broken roads, run out, and can't do their job anymore (thrombocytopenia). The only solution is to fire the bad supplier (deliver the placenta) — then the highways can slowly heal.
