Swallowing triggers its closing over the trachea to prevent food and fluids from draining into our lungs. | | | | 3 | liver | One of the 'accessory' organs of digestion.

It is a pear-shaped sac about 4 inches long and is the reservoir, or storage tank, for bile. Concentrated bile is released into the duodenum as needed to break down fats into an absorbable form. | | | | 5 | common bile duct | As close to a transport highway as we've visited so far. This duct collects donations from the liver and the gall bladder (bile) as it passes along to the duodenum of the small bowel.
