Is there a diagram of the digestive system?
The diagram of the human digestive system is useful for both Class 10 and 12. It is one among the few important topics, which are repetitively asked in the board examinations. The diagram below shows the structure and functions of the human digestive system.
Which is the upper part of the digestive system?
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.
Where does food move in the digestive system?
Find out below. The diagram of the digestive system that is provided in the article will give one a better understanding of this organ system, as the food moves down from the mouth, through the esophagus to the stomach, small intestine and the large intestine, before it is excreted through the rectum and the anus.
What is the function of the esophagus in the digestive system?
Function ~ The esophagus does not have any digestive role. It just helps push down the food from the mouth to the next organ, that is the stomach. This it does by the process of peristalsis. Function ~ The muscles of the stomach churn the food and mix it with gastric juice and enzymes released by the stomach.
Where does the GI tract start and end?
GI tract is a continuous tube extending through the ventral cavity from the mouth to the anus –it consists of the mouth, oral cavity, oropharynx, esophagus, stomach, small intestine, large intestine, rectum, and anus. Accessory structures include the teeth, tongue (in oral cavity), salivary glands, liver, gallbladder, and pancreas.

Where does peristalsis occur in the digestive system?
Peristalsis–wavelike movement that occurs from the oropharynx to the rectum , allowing GI tract to push food particles toward the anus . Mixing—mixing motion in the oral cavity and stomach that allows the GI tract to repeatedly break down food into smaller particles , using mechanical digestion .
Where does mechanical digestion take place in the digestive system?
Mechanical digestion –muscular movement of the digestive tract (mainly in the oral cavity and stomach) physically break down food into smaller particles .
