Your salivary glands make saliva , a digestive juice, which moistens food so it moves more easily through your esophagus into your stomach. Saliva also has an enzyme that begins to break down starches in your food. After you swallow, peristalsis pushes the food down your esophagus into your stomach. Glands in your stomach lining make stomach acid and enzymes that break down food. Muscles of your stomach mix the food with these digestive juices. Your pancreas makes a digestive juice that has enzymes that break down carbohydrates, fats, and proteins. The pancreas delivers the digestive juice to the small intestine through small tubes called ducts.
Your liver makes a digestive juice called bile that helps digest fats and some vitamins. Bile ducts carry bile from your liver to your gallbladder for storage, or to the small intestine for use. Your gallbladder stores bile between meals. When you eat, your gallbladder squeezes bile through the bile ducts into your small intestine. Your small intestine makes digestive juice, which mixes with bile and pancreatic juice to complete the breakdown of proteins, carbohydrates, and fats. Bacteria in your small intestine make some of the enzymes you need to digest carbohydrates.
Your small intestine moves water from your bloodstream into your GI tract to help break down food. Your small intestine also absorbs water with other nutrients. In your large intestine, more water moves from your GI tract into your bloodstream. Bacteria in your large intestine help break down remaining nutrients and make vitamin K. Waste products of digestion, including parts of food that are still too large, become stool. The small intestine absorbs most of the nutrients in your food, and your circulatory system passes them on to other parts of your body to store or use. Special cells help absorbed nutrients cross the intestinal lining into your bloodstream. Your blood carries simple sugars, amino acids, glycerol, and some vitamins and salts to the liver.
Your liver stores, processes, and delivers nutrients to the rest of your body when needed. The lymph system , a network of vessels that carry white blood cells and a fluid called lymph throughout your body to fight infection, absorbs fatty acids and vitamins. Your body uses sugars, amino acids, fatty acids, and glycerol to build substances you need for energy, growth, and cell repair. Your hormones and nerves work together to help control the digestive process. Signals flow within your GI tract and back and forth from your GI tract to your brain. Cells lining your stomach and small intestine make and release hormones that control how your digestive system works.
These hormones tell your body when to make digestive juices and send signals to your brain that you are hungry or full. Your pancreas also makes hormones that are important to digestion. You have nerves that connect your central nervous system—your brain and spinal cord—to your digestive system and control some digestive functions. For example, when you see or smell food, your brain sends a signal that causes your salivary glands to "make your mouth water" to prepare you to eat. When food stretches the walls of your GI tract, the nerves of your ENS release many different substances that speed up or delay the movement of food and the production of digestive juices.
The nerves send signals to control the actions of your gut muscles to contract and relax to push food through your intestines. Griffin P. Rodgers explaining the importance of participating in clinical trials. Clinical trials that are currently open and are recruiting can be viewed at www. The NIDDK translates and disseminates research findings to increase knowledge and understanding about health and disease among patients, health professionals, and the public.

Clinical Trials What is the digestive system? The digestive system Bacteria in your GI tract, also called gut flora or microbiome, help with digestion. Proteins break into amino acids Fats break into fatty acids and glycerol Carbohydrates break into simple sugars MyPlate offers ideas and tips to help you meet your individual health needs. Your digestive system breaks nutrients into parts that are small enough for your body to absorb.
The digestive process starts when you put food in your mouth. As food moves through your GI tract, your digestive organs break the food into smaller parts using: motion, such as chewing, squeezing, and mixing digestive juices, such as stomach acid, bile , and enzymes Mouth. Hormones Cells lining your stomach and small intestine make and release hormones that control how your digestive system works. Fast fact: Thanks to peristalsis, food would get to your stomach even if you were standing on your head! Next stop on our journey through the human digestive system — the stomach! As soon as food plops inside, the stomach lining releases digestive juices and acid that break down the food even more, killing harmful bacteria.
Fast fact: The acid in your stomach is so strong it could dissolve an iron nail! Once all the goodness is gone, the sloppy mixture passes to the next part of the intestines…. They give the lining a large surface area to help with absorbing nutrients. More than twice as wide as the small intestine, but only 1. Finally, the remaining semi-solid waste, called faeces, travels to the lower colon and rectum for storage. When you go to the loo, a ring of muscle called the anus relaxes to allow the poo out!

The role of this green, pear-shaped organ is to store bile a liquid that aids digestion and make it thicker and stronger before adding it to the small intestine. Your pancreas sits just behind the stomach and makes chemicals called enzymes which help digest nutrients in your food. It also makes insulin, a hormone which helps control your blood sugar levels. Doctors used to think that this thin little organ was useless — a leftover body part from early humans.
