Food is broken down physically and chemically as it travels through the digestive system. Nutrients are absorbed into your bloodstream, and remaining wastes are excreted from your body.Esophagus The esophagus is a muscular passageway that connects the mouth to the stomach. Food is moved in one direction toward the stomach by the process of peristalsis – a series of muscle contractions. StomachIn your stomach, food is mechanically broken down and churned physically with stomach juices, or gastric juices, to begin the chemical digestion of proteins.PancreasThe pancreas produces a wide variety of enzymes that are released into the small intestine to cause chemical breakdown of carbohydrates, fats and proteins.LiverThe liver is a large gland that produces and releases bile directly into the small intestine, or to the gall bladder, where it can be stored until it is needed. Bile helps to physically breakdown large fat droplets in foods. Small IntestineAfter being mixed with enzymes from the pancreas and bile from the liver, food is fully digested and the nutrients are absorbed into the walls of the small intestine. The small intestine is about 20 feet long. The stomach releases pepsin into the acidic environment of the stomach. Pepsin chemically breaks down proteins from food into amino acids, which your body needs for many important functions. Organs of the Digestive SystemThe organs of the digestive system are connected, making a long pathway called the digestive tract. Mouth & Oral CavityFood is mechanically broken down by the motion of your tongue and teeth, which breaks the food into smaller particles and mixes it with saliva.Large IntestineThe large intestine serves as a storage organ designed to help form the feces. It absorbs water and small amounts of nutrients, such as Vitamin K, into the bloodstream. pepsin releasedinto stomachpgastriccpitsitspancreasfood parffticlesstomachactsmommto a hs omachsmall intestine(duodenum)pancreatic enzymesliverrammmmmmmmmmmmmmmmyyyyyyyyyyyyyyyyllllllllaaaaaaaaaasssssssseeeeeeeeee llllliiippppppassssseeeeeeeeppprrrooooooootttttttttttteeeeeeeeeaaaaaasePancccccccccccrrrrrrrrrreaaaaaaaaaatttttttttttiiiiiiicccccccccccccccEEEEEEEEEEEnnnnnnnnnnnnnzyyyyyyyyyyyymmmmmmmmmmmmeeeeeeeeeeeeeeeeFFFFFFFFFFFFFFooooooooooooooooooooooddddddddddddddddd parFFFFFFFFFFFFFttttttiiiiiiiicccccccccccccllllllllllleeeeeeeeeeeeSSSSSSSSSSSSSSSSiiiiiiiimmmmplestttttttttttttt ffffffffffffooooooooooorrrrrrmmmmmmmmmmm((((((((mmmmmmmmmmmmmmmooooooooooooollllllllleeeeeeeeeeeeecules)))))))))cccccccccaaaaaaaaaaarrrrrrrrrrbbbbbbbbbbbbohhhhhhhhhhhhhyyyyyyyyyyyydddddddddddddrrrrrrrrrrrraaaaaaaaattteeeeeeeeesssssssssssssproteinsfatssimplee sssssssssuuuuuuuuuuuggggggggggggggaarrrrrrrssssssssssssaaaammmmmmmmmmmmiiiiiiiiinnnnnnnnnnoooooooo aaaaaaaaaacccccccccccciiiiiiiddddddddddsssssssssssstriglyceridddddddddeeeeeeeeeeessssssssssssfattttttttttttttttttttttttyyyyyyyyyyy aaaaaaaaaaaaccccidsYour digestive system processes the food and drink you consume.
