Pharynx –It is a fibromuscular, Y-shaped tube-like structure, attached to the terminal end of the mouth. It is involved in the passage of chewed food from the mouth through the esophagus.
Esophagus —This is a muscular tube, measuring 25 cm long and located near the trachea connecting to the pharynx. It is the upper part of the gastrointestinal tract and is mainly involved in delivering the food particles from the mouth to the stomach.
Stomach –It is a hollow and muscular organ, situated towards the left side of the abdominal cavity and beneath the diaphragm. It is a vital organ, which functions by storing the food, provides enough time to digest meals, produces hydrochloric acid and digestive enzymes that maintain the process of digestion.
Small Intestine –It is a thin and long tube-like structure measuring about 9 to 10 feet long and also the part of the lower gastrointestinal tract. The small intestine is located just behind the stomach, which is found completely coiled and consists of folds and ridges.

It is present just beneath the stomach and wraps over the superior and lateral edges of the small intestine.
