Appendix -The appendix sits at the junction of the small intestine and large intestine. It’s a thin tube about four inches long. Normally, the appendix sits in the lower right abdomen. The function of the appendix is unknown. One theory is that the appendix acts as a storehouse for good bacteria, “rebooting” the digestive system after diarrheal illnesses.
Duodenum – The duodenum’s location is just beneath the stomach, and sits to the right of the body. Its function are chyme processing and nutrient absorption.
Esophagus – The esophagus begins at the throat (pharynx) and travels to the stomach, passing through the diaphragm en route. The esophagus serves to pass food and liquids from the mouth down to the stomach. This is accomplished by periodic contractions (peristalsis) instead of gravity.
Large intestine – The large intestine is the terminal segment of the human gastrointestinal (GI) tract, which is a continuous, tube-like channel via which food passes along the human digestive system. It runs from the small intestine to the anal canal, wherein food waste is eliminated. In simpler terms, the large intestine is involved in faeces production.
Ileum – Its main function is to absorb vitamin B 12, bile salts, and whatever products of digestion that were not absorbed by the jejunum. The ileum follows the duodenum and jejunum and is separated from the cecum by the ileocecal valve (ICV).
Stomach – The stomach is the most dilated part of the digestive system, lying between the esophagus and duodenum. The main function of the stomach involves mechanical and chemical digestion of ingested food.
Liver – Your liver is located on the right side of your body in the upper right abdomen below your ribcage. The liver is one of the largest internal organs in your body and its main function is to filter blood and remove toxins. Your liver also plays an important role in your digestive system.
Gallbladder – The gallbladder is an organ that’s found in your abdomen. Its function is to store bile until it’s needed for digestion. When we eat, the gallbladder contracts, or squeezes, to send bile into your digestive tract.
Jejunum – The jejunum is the middle of the three parts of the small intestine between the duodenum and ileum. It plays an important role for digestion as 40% of the whole small intestine is jejunum.
Pancreas – The pancreas is located behind the stomach in the upper left abdomen. It makes pancreatic juices, which contain enzymes that aid in digestion, and it produces several hormones, including insulin.
