Foods That Trigger Diarrhea Esophagus Once food is swallowed, it enters the esophagus, a muscular tube that is about 10 inches long.
Bacteria in the large intestine can also break down food. How does food move through my GI tract? 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.
The digestive process starts when you put food in your mouth.
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. 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 chymeinto your 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. As peristalsis continues, the waste products of the digestive process move into the large intestine.
Waste products from the digestive process include undigested parts of food, fluid, and older cells from the lining of your GI tract.
The large intestine absorbs water and changes the waste from liquid into stool. Peristalsis helps move the stool into your rectum. The lower end of your large intestine, the rectum, stores stool until it pushes stool out of your anus during a bowel movement.
How does my digestive system break food into small parts my body can use? As food moves through your GI tract, your digestive organs break the food into smaller parts using: The digestive process starts in your mouth when you chew.
Your salivary glands make salivaa 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.Anatomy of the Digestive System Topic Guide Anatomy of the Digestive System Facts Digestion is the process by which food is broken down into smaller pieces so the body can use them to build and nourish cells and to provide energy.
