Liver ; The liver's main job is to filter the blood coming from the digestive tract, before passing it to the rest of the body. The liver also detoxifies chemicals and metabolizes drugs. As it does so, the liver secretes bile that ends up back in the intestines. The liver also makes proteins important for blood clotting and other functions.
pancreas; A healthy pancreas produces the correct chemicals in the proper quantities, at the right times, to digest the foods we eat.
The endocrine component of the pancreas consists of islet cells (islets of Langerhans) that create and release important hormones directly into the bloodstream. Two of the main pancreatic hormones are insulin, which acts to lower blood sugar, and glucagon, which acts to raise blood sugar. Maintaining proper blood sugar levels is crucial to the functioning of key organs including the brain, liver, and kidneys.
epiglottis; The main function of the epiglottis is to seal off the windpipe during eating, so that food is not accidentally inhaled. The epiglottis also helps with some aspects of sound production in certain languages.
