An Overview of the human digestive system, including its parts and Functions

The human digestive system is a complex network of tissues and organs that break down food and ingest nutrients. It removes necessary nutrients from food and eliminates waste products from our bodies. In this article, we will learn about the digestive system’s different parts and functions.


Beginning with the mouth, the digestive process begins. It has salivary glands that digest food, teeth, and a tongue. The tongue moves food around the mouth as the teeth grind and chew Saliva from the salivary glands includes enzymes that break down carbohydrates.


A muscular tube called the esophagus joins the mouth to the stomach. In order to transfer food into the stomach, muscles flex.


The muscular sac that makes up the stomach blends and grinds food with digestive secretions. It produces hydrochloric acid and enzymes that break down proteins. The stomach also discharges chyme, a semi-liquid mixture of food and gastric secretions, into the small intestine.

Small intestine

Adults have a small intestine that is a 20-foot-long, long, and narrow tube. It is separated into the ileum, jejunum, and duodenum. Villi, which resemble tiny finger-like extensions on the small intestine wall, increase the absorption surface area.


The pancreas is a gland behind the stomach that creates hormones and digestive enzymes. The pancreas produces digestive enzymes and breaks down proteins, lipids, and carbohydrates in the small intestine.


Located on the upper right side of the belly, the liver is a sizable organ. It produces bile, a greenish-yellow fluid that breaks down fats in the small intestine. The liver also plays a role in nutrient metabolism and harmful substances detoxification.


Under the liver located a little, pear-shaped organ called the gallbladder. It stores and releases bile into the small intestine to aid in fat digestion.

Large intestine

The large intestine, also known as the colon, is a wide tube about 5 feet long in adults. It absorbs water and electrolytes from remaining food waste and forms them into feces. The feces are stored in the rectum and then removed from the body through the anus.
