1. Esophagus – The esophagus is a muscular tube that connects the pharynx (throat) to the stomach (esophagus). The esophagus is around 8 inches length and coated with mucosa, a moist pink tissue. The esophagus is located behind the windpipe (trachea), in front of the heart, and behind the spine.
2. Duodenum – The small intestine’s initial section. It is linked to the stomach. The duodenum aids in the digestion of food that has passed through the stomach. It absorbs nutrients (vitamins, minerals, carbs, fats, proteins), as well as water, from meals so that the body may use them.
3. Ileum – The small intestine’s last section. It attaches to the cecum (first part of the large intestine). The ileum aids in the digestion of food that has passed through the stomach and other portions of the small intestine.
