Your brain needs a lot of energy to run, but it’s also the only organ that isn’t capable of producing its own energy. It is entirely dependent on oxygen and glucose being constantly fed to it.
The heart pumps the juice to the squash. If the pump suddenly stops working, it doesn’t matter if there’s good stuff in the juice if it can’t go anywhere.
This is different from a respiratory / airway issue where there’s plenty of juice going to the squash, it’s just not good juice.
