The small intestine is a basic and important part of our body for overall health of the body, which is responsible, among other things, to digest and absorb nutrients. When the food reaches the small intestine is no longer recognized, what you have eaten is at this point a mass of which we absorb nutrients and the goes into the large intestine as waste material.
The small intestine is situated in the abdominal cavity, is a shaped elongated tube; it is hollow and has thin walls in its villus. It measures about 8 feet long and is folded or twisted repeatedly.
The intestine is divided into three parts: the duodenum, where starts and connects to the stomach, jejunum, the middle, and the ileum is the final section.
The muscles of the large intestine help to mobilize food and bolus between the villi of the walls, full of tiny blood vessels, which are responsible for absorbing nutrients that go through the pancreatic juice and the bile produced by the liver. The bile helps to absorb fats while pancreatic fluid completes the digestion of proteins and sugars (which began in the stomach by the intestinal juice, produced by the walls of the small intestine).
Once this process is complete then assimilation of food nutrients by the villi of the small intestine happens, which has capillaries that carry nutrients throughout the body. This passage of nutrients into the blood is called absorption.
On the walls of the large intestine mucosa are the Brunner glands (which secrete mucus) and Lieberkühn (secreting intestinal juice). The result of this movement is glandular:
Once this occurs, the digestion is complete and the product must pass through the intestinal wall (absorption), so that enter the bloodstream and can be carried to every cell in the body.
Symptoms of these conditions can be very varied.
For example, in the case of a bowel obstruction, when the food or fecal material cannot leave the small intestine, either partially or completely, and by various causes such as adhesions, hernias, cancer, etc., pain symptoms may be accompanied by cramping abdominal pain, frequent vomiting, swollen belly, accented gas, constipation, etc.. In case of complete obstruction should be addressed immediately.
In the case of irritable bowel syndrome, the person may have frequent heartburn abdominal pain, vomiting, etc.
To maintain the health of the small intestine is very important to follow these recommendations:
