What else does the intestine absorb besides nutrients?

Many people know that most of the nutrients in the food we eat are absorbed in the intestines. As they move in the large intestine, the energy and nutrients they contain are fully absorbed by the large intestine. So, what about the other remaining substances? Can the large intestine absorb? So many people ask what else the intestine absorbs besides nutrients. The editor also seems to understand it, so let us look at the information together.

The large intestine itself has the ability to absorb food. When food residues pass through the large intestine, the large intestine will try its best to recycle everything that can be recycled. The most obvious thing is water, of course there are other nutrients as well. It cannot be ruled out that the condition is caused by weak spleen and stomach. You can take Bupi Yichang Pills and Renshen Jianpi Pills for treatment. Eat a balanced and light diet, eat more vegetables and fruits, and avoid spicy and cold foods. According to your description, the intestines mainly absorb nutrients and excrete and transport the absorbed residues to form feces and are excreted from the body. This is basically their function.

Structure function

Cecum

Cecum

It is the enlarged blind end of the beginning of the large intestine, about 6 to 8 cm long, located in the right iliac fossa, connecting to the ascending colon upward and the ileum to the left. The connecting opening between the ileum and cecum is called the ileocecal opening. The mucous membrane at the mouth is folded into two semi-lunar folds, called the ileocecal valve. This valve acts as a sphincter and prevents the contents of the large intestine from flowing back into the small intestine. The opening of the appendix is ​​located approximately 2 cm below the ileocecal valve.

appendix

The appendix is ​​shaped like an earthworm and is also called the lumbrical process. The upper end is connected to the posterior inner wall of the cecum

The large intestine is free at the lower end and is generally about 2 to 20 cm long and about 0.5 cm in diameter. The mesoappendix is ​​attached to the entire length of the appendix and is more mobile.

The projection position of the root of the appendix on the body surface is usually marked by the junction of the outer and middle 1/3 of the line connecting the umbilicus and the right anterior superior iliac spine, clinically called McBurney's point; or by the junction of the middle and right 1/3 of the line connecting the left and right anterior superior iliac spines, clinically called Lanz's point. Tenderness may occur at this point in acute appendicitis.

colon

The colon is the part between the cecum and the rectum. According to its location and shape,

It is divided into four parts: ascending colon, transverse colon, descending colon and sigmoid colon.

(1) Ascending colon

It is about 15 cm long and is the upward continuation of the cecum. It rises from the right iliac fossa along the right side of the posterior abdominal wall, bends left in the direction below the liver to form the right flexure of the colon, and then transitions to the transverse colon. The posterior part of the ascending colon is attached to the posterior abdominal wall by connective tissue, so it has less mobility.

(2) The transverse colon is about 50 cm long and starts from the right flexure of the colon, runs horizontally to the left to the spleen and then bends downward to become the left flexure of the colon.

, migrates to the descending colon. The entire transverse colon is covered by peritoneum and connected to the posterior abdominal wall by the transverse colon mesentery. The middle part is sagging and has greater mobility.

(3) The descending colon is about 20 cm long. It starts from the left flexure of the colon, descends along the left side of the posterior abdominal wall, and transitions to the sigmoid colon at the left iliac crest. The back of the descending colon is attached to the posterior abdominal wall by connective tissue, so it has little mobility.

(4) The sigmoid colon is about 40-45 cm long. It connects to the descending colon at the level of the left iliac crest and curves in the shape of an “I” until it reaches the front of the third sacral vertebra and becomes the rectum. When empty, its front is often filled with small intestine

Covered, when filled and dilated, it is palpable in the left iliac fossa. The sigmoid colon is completely covered by peritoneum and is connected to the left iliac fossa and the posterior wall of the small pelvis by the sigmoid colon mesentery, and it has great mobility.

After reading the above information, I realized that the intestines play such an important role in the human body. It is not only responsible for absorbing most of the nutrients in food. It can also absorb other substances at the same time. The effects on the intestines have been introduced in detail above. You can go and find out. At the same time, you should also pay attention to protecting your intestines in your life.
