Homeostasis is a big concept, reduced to a few meaningless words in biology class.
If you want to be cognizant of how things work, focus on how they fail.
Death is rarely pretty (however lovely the swirls of pathogens on a Petri dish look). I have seen many people die, have felt the heat of life slip away as a corpse, moments before a body, no longer fights the inevitable heat death of the universe.
Biology in high school can be immensely boring. Death less so. Especially one’s own.
