The GI tract is where food travels after leaving your mouth and passing through your stomach, esophagus, and small and large intestines. Nutrients and water from food are absorbed in the GI tract to keep your body healthy. Anything that isn't absorbed passes through your GI tract until you eliminate it in the bathroom.
Peristalsis is the physiological process through which food passes through your GI tract. Your GI tract's big, hollow organs are covered in a layer of muscle that allows the walls to move. The motion mixes the contents of each organ as it forces food and liquid through your GI tract.
Due to the peristaltic waves that move food to the stomach, it may be said that food considerably reaches the stomach regardless of a person's position. These waves are so powerful that they will cause the same problem even if a human is hanging upside down or an astronaut is eating in zero gravity.
The colon, rectum, and anus are all parts of the large intestine. As food approaches the end of its journey through your digestive system, it continues in one continuous, lengthy tube from the small intestine. When you defecate, the large intestine removes food waste from the body by converting it into stool.
Through tiny passageways known as ducts, bile and enzymes are transported into the small intestine where they aid in the digestion of food. The large intestine receives partially digested food and some water via a muscular ring known as the ileocecal valve (ill-ee-oh-SEE-kul).
Final response: The small intestine is where food is primarily digested and absorbed.
The following is the order in which food moves through the digestive system:Mouth, esophagus, stomach, small and large intestines, colon, and rectum make up the human body.
The lower esophageal sphincter (LES), a valve, is situated right before the stomach's opening. This valve stops food from traveling back up into the esophagus from the stomach and opens to allow food to move from the esophagus into the stomach.
The esophagus is a muscular tube that connects the hypopharynx to the stomach, measuring about ten inches (25 cm) in length. In its descend from the thoracic to the abdominal cavity, the esophagus passes through the mediastinum and the hiatus, a hole in the diaphragm, which are located posterior to the trachea and the heart.
EsophagusEsophagus. The esophagus is roughly 25 cm (10 inches) long and 1.5 to 2 cm (about 1 inch) wide. It transports food from the pharynx to the stomach.
