The digestive system is a combination of digestive organs that work in coordination to digest food, absorb the essential substances into the bloodstream and defecate or eliminate undigested material out of the body. The food that you intake is converted into energy and useful nutrients your body needs. The digestive system is composed of an oral cavity that starts from the mouth, esophagus, stomach, small intestine, large intestine, and liver.

The digestive system is described as:

Mouth: The breaking down of larger food into smaller pieces occurs in the mouth. Saliva is also present in the mouth. Enzymes in saliva accelerate food digestion.
Esophagus: A tube that pushes food downs from mouth to stomach.

Stomach: When food reaches stomach it is further digested due to the acidic environment of the stomach. The pH here is low. It breaks food into more small chunks and food then enters the small intestine.

Small intestine: The digestion of carbohydrates, proteins, and lipids occurs here due to the presence of enzymes like lipase, protease, and amylase. The food is converted into a useful form that enters the bloodstream through walls of the small intestine.

Large Intestine: The organ next to the small intestine is the large intestine. The undigested waste enters here. Water is absorbed from the walls of large intestines. The harmful matter is defecated as it is not further needed by the body.

Liver: It is the largest organ of our body. It is located above the stomach. It secretes bile through the bile duct into the small intestine. This helps in the digestion of food.
