The intestines are a vital part of the digestive system, responsible for absorbing nutrients and water while processing food from the stomach to the anus. The intestines include the small intestine, large intestine, and rectum, each playing a crucial role in digestion and overall gut health.
If you’re experiencing digestive issues, abdominal pain, or irregular bowel movements, consult Dr. Ujwal Zambare, best gastroenterologist in Wakad, Pune, for expert diagnosis and treatment.
The small intestine is made up of three segments, which form a passage from your stomach (the opening between your stomach and small intestine is called the pylorus) to your large intestine:
By the time food reaches your small intestine, it has already been broken up and mashed into liquid by your stomach. Each day, your small intestine receives between one and three gallons (or six to twelve liters) of this liquid. The small intestine carries out most of the digestive process, absorbing almost all of the nutrients you get from foods into your bloodstream. The walls of the small intestine make digestive juices, or enzymes, that work together with enzymes from the liver and pancreas to do this.
Looking at the small intestine as a pipe, it seems hard to believe that an organ so narrow could do such a big job. However, looks can be deceiving. The absorptive surface area of the small intestine is actually about 250 square meters (almost 2,700 square feet) – the size of a tennis court! How is this possible? The small intestine has three features which allow it to have such a huge absorptive surface area packed into a relatively small space:
Your large intestine is about five feet (or 1.5 meters) long. The large intestine is much broader than the small intestine and takes a much straighter path through your belly, or abdomen. The purpose of the large intestine is to absorb water and salts from the material that has not been digested as food, and get rid of any waste products left over. By the time food mixed with digestive juices reaches your large intestine, most digestion and absorption has already taken place.
What’s left is mainly fiber (plant matter which takes a long time to digest), dead cells shed from the lining of your intestines, salt, bile pigments (which give this digested matter its color), and water. In the large intestine, bacteria feed on this mixture. These helpful bacteria produce valuable vitamins that are absorbed into your blood, and they also help digest fiber. The large intestine is made up of the following parts:
If you are experiencing persistent digestive issues, abdominal pain, bloating, or changes in bowel habits, it’s important to seek medical attention. Early diagnosis and treatment can help prevent complications.
