eli5 Why are air embolisms so deadly? Like, what about an air bubble can’t your body fix pretty easily?

I would have thought that an air bubble gets popped and we move on. That the gas eventually dissolves and gets passed somehow.

So, what’s going on? Why does the heart stop so violently? It acts like there was an implosion on the inside…

Our body doesnt work like a lake or river, where the air from the “popped” bubble can just rise up and escape into the atmosphere.

Our circulatory systems are closed systems, meaning nothing should be going in or out. When an air embolism forms it typically ends with the embolism traveling into the heart and then the lungs since air is lighter than blood and plasma. This can cause a number of complications that belong in another thread, none of which are easy to fix.

And even worse than ending up in your heart, is if the embolism ends up lodged in your brain.
