Hydrochloric acid Mucus Pepsinhydrochloric acid mucus pepsin
The stomach is protected from acid by mucus, a slippery substance. The mucus covers the inside of the whole stomach. If there is a patch of mucus that is not there then it will cause a lot of pain from the acid.
Uric acid is primarily produced by birds, reptiles, and some terrestrial invertebrates, such as insects and arachnids. These animals excrete nitrogenous waste in a semi-solid form, which helps conserve water, making it advantageous for survival in arid environments. In addition, certain mammals, like the giant ground sloth, also produced uric acid, though most mammals primarily excrete urea.
They excrete faeces and uric acid from their cloaca.

A lining of mucus is what protects ur stomach from hydrochloric acid
Animals excrete a variety of substances through the excretory and respiratory systems. Three things they excrete are carbon dioxide, uric acid, and ammonia.
The stomach wall is protected by mucus. The mucus regenerates about every 2 weeks or so.
Because we have a thick layer of mucus surrounding the lining of our stomach. The mucus is strong enough to withstand the acid.
The end product of filtration and re-absorption in the kidneys is urine.
