What are the digestive organs of the human body

Our human body is a very complex system. The digestive system alone is divided into the upper digestive tract and the lower digestive tract. From our mouth to our large intestine, they all belong to the digestive tract. There are also many branches in the small intestine and large intestine in the digestive tract. The liver, pancreas, and salivary glands are also digestive glands in the digestive organs. This article introduces the details of the human digestive organs. If you want to know more about this, let’s take a look.

1. What are the digestive organs in the human body?

The human body's digestive organs are composed of the digestive tract and digestive glands. The digestive tract includes: mouth, pharynx, esophagus, stomach, small intestine (duodenum, jejunum, ileum) and large intestine (iliac colon, appendix, ascending colon, transverse colon, descending colon, sigmoid colon, rectum). The digestive glands include: salivary glands (parotid glands, submandibular glands, sublingual glands), liver (gall bladder), and pancreas.

1. Oral cavity

In fact, we have already digested food starting from our mouth. When we are eating, we often hear our family members say that we should chew food slowly. In fact, this statement makes sense. By chewing food slowly, we can bite the food more thoroughly, making the nutrients in the food easier to absorb and more conducive to the subsequent digestion process. At the same time, we also have digestive enzymes in our mouths that can also help us digest food.

2. Stomach

The stomach is the digestive organ we are most familiar with. We all know that the stomach mainly digests food through gastric acid. In fact, to be more specific, the main function of the stomach is decomposition, which is to decompose it through various enzyme substances. On the one hand, it helps us better digest a food and absorb its nutrients. On the other hand, it is also beneficial to the subsequent digestion process.

3. Small Intestine

The small intestine is an important digestive organ in our body. The nutrients of the food we eat are mainly absorbed through the small intestine. That is to say, whether it is chewing in the mouth or decomposing food in the stomach, it lays the foundation for the small intestine to better absorb the nutrients inside. There are various enzymes in the small intestine that can fully absorb the broken down food.

4. Large Intestine

The large intestine is the last organ to work in the digestion process in our body. However, what enters the large intestine from the small intestine are basically the final products and waste that have been almost digested. The large intestine can further absorb the water and salt substances in the food residue, and then the remaining waste will form feces in the large intestine and be excreted from the body.
