Some Accessory Organs These next 2 organs you will look at doesn’t actually touch the food. They produce things that help with digestion.
Liver The Liver liver In the digestive system, the liver produces bile which breaks down fat particles into small droplets. Bile is stored in the gall bladder.
Pancreas The Pancreas pancreas After bile from the liver breaks down the fat the pancreas produces enzymes to break down starches, proteins, and fats.
Primary Organs Now let’s rejoin our Snickers bar. It is just leaving the stomach.
Small Intestine The Small Intestine small intestine The small intestine is where most of the chemical digestion takes place. As liquid moves through the small intestine it mixes with enzymes from the liver and the pancreas. small intestine The small intestine absorbs most of the nutrients that we use.
Absorption Absorption in the Small Intestine The small intestine have many millions of tiny finger-shaped structures called villi. These villi increase the surface area and allow for more nutrients to be absorbed. The circulatory system carries the nutrients to the rest of the body.
Large Intestine The Large Intestine large intestine The large intestine is where the remaining water is removed from the mixture of nutrients. We have many bacteria that help us to break down this mixture. large intestine The remaining water is reabsorbed by the large intestine. large intestine After the large intestine the material is compressed by the rectum.
