Human digestion

1.Digestive Organs

Available 12 human digestive organs that play a role in the process of digestion of food in the body. These organs are integrated with each other to form a digestive system. The human digestive system starts from the mouth and ends in the anus. The following is an illustration of the digestive system in the human body:

2.Human Digestive System

The human digestive system consists of two digestions namely mechanical and chemical. The process starts from mechanical digestion that occurs in the mouth. Then proceed with chemical digestion by enzymes in other digestive organs.

a. Mechanical Digestion

Mechanical digestion occurs in the mouth and stomach. The process that occurs in the mouth involves the teeth for mechanical movements in digesting food. Meanwhile, in the stomach there is mechanical digestion in the form of movements such as stirring or squeezing food. Mechanical movements in the stomach are moved by smooth muscles.

In carrying out the process, teeth are also many of the most common ways to eat everyday. If categorized, There are three types of teeth that play a role in digesting food in the mouth, that is:

1. Incisor (Incisor) – function to cut food.
2. Teeth (Canine) – serves to tear and tear food.
3. Molars (Premolar & Molar) – serves to make food more efficient.
b. Chemical Digestion

Chemical digestion is carried out by enzymes. Enzymes are proteins that act as biocatalysts in the body. The enzymes that play a role in the process of chemical digestion, among others:

1. Amylase: This enzyme is produced by the salivary glands. Inside the mouth, This enzyme works to break down the starch into maltose.
2. Protease: This enzyme is produced in the stomach and pancreas, It breaks down proteins into amino acids.
3. Lipase: produced by the pancreas, works to break down fat (lipid) into fatty acids and glycerol.
4. Maltase: Maltase enzyme is produced in the small intestine, serves to break down maltose into glucose.
that's the mechanism of human digestive organs in the body. The existence of knowledge about the digestive organs can make us to always be careful. That means, wise in choosing good foods for our digestive organs. Healthy food, clean, and nutritious are very important parameters to maintain a healthy body. So, always take care of your digestive organs .
