Well, as a human being I can’t say this applies to me. Sure, some animals (like the jellyfish, sea anemones, and coral) defecate and consume food through the same orifice mainly because they lack a through-gut. instead they have a single-opening gastrovascular cavity. Some comb jellies also fall into this category, of ewhich one species, the warty comb jelly, seems to develop a temporary anus for excretion. I have no information about farting.
