Our colon, or otherwise known as our large intestine, is the second longest part of our digestive tract. aged care facilities The large intestine plays a vital role in digestion, and without it our body would be unable to remove waste from the body.
When people think of the digestive system, many do in fact think of the small and large intestines. It is a crucial portion of the gastrointestinal tract and is considered the last area where nutrient absorption can take place.
The large intestine is about 5 feet long and 2.5 inches in diameter. It starts at the ileum, which is the end portion of the small intestine, and ends at the anus.
There are 4 major areas of the large intestine where absorption takes place.
These are the:
and the anal canal
The opening of the large intestine is where the cecum is, and attached to the cecum is our appendix. The main tube of our large intestine is called the colon. This is the main area where food that will eventually turn to stool passes through.
The rectum is a mere 8 inches long, much smaller than the rest of the large intestine. The passageway to the anus is the anal canal, and that is where feces are eliminated.
The main purpose of the large intestine is for water to be taken back by the body. Liquid is entering the large intestine from the small intestine, and this liquid needs to be turned into a solid. As the liquid passes through the colon, the mucosal walls are absorbing water from the liquid, thus turning it into a solid stool.
By the end of the colon, the stool has no liquid components to it. Feces consist of very little water, inorganic salts, products from bacterial decomposition, any materials that are unabsorbed by the body, and indigestible parts of the food we have eaten. The large intestine has the job of turning chyme, the liquid breakdown of the food we ate, into feces.
The large intestine is an extremely important part of our digestive system. It does extreme turning and churning of chyme (liquid “food”) into feces. The colon walls push the contents found inside to the rectum.
Also in this process, bacteria are producing chemicals that break down the contents of the intestine even further. The main function of the large intestine is to absorb the last bits of water from the chyme, and turning it into feces and thus removing it from the body.
Keeping your large intestine healthy is extremely important. Those with bad diets end up having intestinal issues.
For example, those who drink massive amounts of protein drinks could end up having problems in the large intestine due to the high amount of protein they have been taking in.
Some other common issues of the large intestine include irritable bowel syndrome (IBS) and also chronic constipation. Keeping your large intestine clean and healthy is important for proper function of all parts of the large intestine.
