Great! Get to Know the Human Body's Digestive Process Starting from Digestion to Absorption

Digestion is an important process in the human body that aims to process food into substances that can be absorbed by the body. This process involves several digestive organs that work together to digest food efficiently.

Human Digestive Organs

The following is digestive organs in the human body along with the function of each organ:

  1. Mouth: The mouth is where the digestion process begins. In the mouth there is saliva that contains the enzyme amylase to break down carbohydrates.
  2. Esophagus: The esophagus is a tube that connects the mouth to the stomach. Its function is to transport food from the mouth to the stomach.
  3. Stomach: The stomach is an organ that produces gastric acid and enzymes to digest proteins. Food that has been processed in the stomach is called chemical acid.
  4. Small intestine: The small intestine is the main place for absorption of nutrients from food. In the small intestine, further digestion occurs with the help of digestive enzymes.
  5. Colon: The large intestine plays a role in absorbing water and mineral salts from food residue that is not digested by the small intestine.
  6. Temporal Arch: This section is a temporary storage place for food waste before it is excreted from the body in the form of feces.

Food Digestion Process

Process food digestion consists of several interrelated stages. The following are the stages of the food digestion process:

  1. Ingest: The stage where food enters the mouth.
  2. Bolus Formation: Food that is put into the mouth is processed and formed into a bolus before being swallowed.
  3. Peristalsis of the Esophagus: The movement of the esophageal muscles that pushes food towards the stomach after it is swallowed.
  4. Digestion Process in the Stomach: In the stomach, food is further digested with the help of stomach acid and digestive enzymes.
  5. Absorption of Nutrients in the Small Intestine: Nutrients from food are absorbed by the small intestine and enter the bloodstream to be distributed throughout the body.
  6. Formation of Feces: Undigested food waste is converted into feces in the large intestine before being excreted from the body.


Indigestion can occur due to various factors, such as unhealthy diet, stress, or infection. Some common digestive disorders include:

  • Gastric pains: Disorders caused by excessive production of stomach acid which damages the lining of the stomach.
  • GERD (Gastroesophageal Reflux Disease): A disease caused by the return of stomach acid into the esophagus, causing a burning sensation in the chest.
  • Diarrhea: A condition where the stool becomes loose and the frequency of bowel movements increases due to infection or food intolerance.
  • Flatulence: The stomach feels full and bloated due to the accumulation of gas in the digestive tract.
  • Dyspepsia: Digestive disorders characterized by symptoms such as bloating, abdominal pain, and nausea.

Tips for Maintaining Digestive Health

To maintain digestive health, here are some tips and preventive measures what can be done:

  1. Eat Regularly: Avoid eating too fast or too slow, and try to eat at the same time every day.
  2. Fiber Consumption: Fiber helps smooth digestion and prevents constipation.
  3. Avoid Fatty and Spicy Foods: Fatty and spicy foods can trigger digestive disorders such as ulcers and GERD.
  4. Drink a lot of water: Water helps improve digestion and prevent dehydration.
  5. Exercise Regularly: Exercising regularly can increase metabolism and speed up the digestion process.


Digestion in the human body is a complex process involving various digestive organs to digest food into substances that can be absorbed by the body. By maintaining a healthy diet and an active lifestyle, we can prevent digestive disorders and maintain overall body health.
