Digestive system how many organs

Enzymes convert dissolved food from the stomach into energy the body can use. These organs —liver, gallbladder, and pancreas— perform many functions that aid digestion, as well as maintain a regulated energy flow to the rest of the body. These enzymes are delivered into the duodenum via the biliary tract or biliary tree.

With so many organs performing so many functions in your digestive system, the number of things that can go wrong is vast. However, problems can be broadly categorized:.

Instead, the bile enters the bloodstream, which can cause your skin, eyes, and nails to appear yellow. The pancreas, liver, and gallbladder are considered accessory organs. Food does not move through them, as it does in the gastrointestinal tract, but these organs release hormones and chemicals that are essential to digestion.

In type 1 diabetes, your pancreas does not produce insulin, causing your blood sugar to rise.

The colon is next. The rectum is the end of the large intestine. Bacteria in your GI tract, also called gut flora or microbiome, help with digestion. Parts of your nervous and circulatory systems also help. Working together, nerves, hormones , bacteria, blood, and the organs of your digestive system digest the foods and liquids you eat or drink each day.

Digestion is important because your body needs nutrients from food and drink to work properly and stay healthy. Proteins , fats , carbohydrates , vitamins , minerals , and water are nutrients. Your digestive system breaks nutrients into parts small enough for your body to absorb and use for energy, growth, and cell repair. MyPlate offers ideas and tips to help you meet your individual health needs. Each part of your digestive system helps to move food and liquid through your GI tract, break food and liquid into smaller parts, or both.

Once foods are broken into small enough parts, your body can absorb and move the nutrients to where they are needed. Your large intestine absorbs water, and the waste products of digestion become stool. Nerves and hormones help control the digestive process. Food moves through your GI tract by a process called peristalsis. The large, hollow organs of your GI tract contain a layer of muscle that enables their walls to move.

The movement pushes food and liquid through your GI tract and mixes the contents within each organ. The muscle behind the food contracts and squeezes the food forward, while the muscle in front of the food relaxes to allow the food to move. Food starts to move through your GI tract when you eat. When you swallow, your tongue pushes the food into your throat. A small flap of tissue, called the epiglottis, folds over your windpipe to prevent choking and the food passes into your esophagus.

Once you begin swallowing, the process becomes automatic. Your brain signals the muscles of the esophagus and peristalsis begins. Lower esophageal sphincter. When food reaches the end of your esophagus, a ringlike muscle—called the lower esophageal sphincter —relaxes and lets food pass into your stomach.

After food enters your stomach, the stomach muscles mix the food and liquid with digestive juices. The stomach slowly empties its contents, called chyme , into your small intestine. Small intestine. The muscles of the small intestine mix food with digestive juices from the pancreas, liver, and intestine, and push the mixture forward for further digestion. The walls of the small intestine absorb water and the digested nutrients into your bloodstream.
