Intestine: nutrient and water absorption
The gut is part of the digestive system and it is through it that nutrient and water uptake occur.
Knowing the gut (main features)
It is divided into two parts: slender and thick. In the first is where the absorption of the vast majority of nutrients occurs. In the second, most of the water used during the digestion process is absorbed.
The absorption of water by the large intestine is responsible for the firm consistency of the stool. The lack of this consistency is known as diarrhea, which may occur due to factors such as viruses, digestion disorders, etc.
In these cases, it is important for the individual to stay well hydrated, drink plenty of water and seek medical advice.
The small intestine has the following layers: mucosa, submucosa, muscle and serosa. The first layer (mucosa) has smooth muscle and secretion of enzymes and juices occurs in it.
This smooth muscular layer of the mucosa is divided into duodenum, jejunum and ileum. The duodenum is its first portion, it goes from the pylorus to the jejunum. It is in this region that the food cake is worked by the action of the enteric juice.
In the jejunum and ileum, nutrients are absorbed, which pass into the bloodstream and liver to be distributed throughout the body.
A high fiber diet makes the intestines work well.
