@instituteofhumananatomy: "Toxin" doesn't just mean the scary stuff on an ingredient label. ☠️ A toxin is any substance that can harm your body — and some come from inside you. The ones from outside (alcohol, medications, pollutants) are exogenous. But your own cells constantly produce endogenous toxins too: carbon dioxide from making energy, ammonia from breaking down protein (your liver converts it to safer urea before it builds up). Here's the key: toxicity is usually dose-dependent. Most substances aren't inherently harmful at low levels — they become dangerous when they accumulate. Even water can turn deadly if you drink too much too fast. 💧 The dose makes the poison. 🔬 #tiktoklearningcampaign #toxicology #physiology #anatomy #humanbody #livershealth #metabolism #biology #anatomyandphysiology #dosemakesthepoison #detox #cellularrespiration #medstudent #sciencefacts #healthscience #iohaanatomy Follow for more anatomical awesomeness
