Explanation:
The large intestine has 3 primary functions: absorbing water and electrolytes, producing and absorbing vitamins, and forming and propelling feces toward the rectum for elimination
Answer:
The function of the large intestine is not only limited to the formation of feces. Rather it covers a huge arena of functionality.
The large intestine helps in the formation of stool. The undigested food particles are passed through the entire four sections of the colon. The colon walls absorb the water and other fluids from the undigested food and facilitate the solidification of the liquid. As a result, feces are formed. The absorbed water is important for controlling metabolism in our body.
The undigested food should not stay for too little time or too long time within the colon. The former will cause less or minimal absorption of water and hence will lead to diarrhea. The later will cause excess water absorption and hence constipation.
The large intestine is the hub of many useful bacteria that help in the breakdown of the undigested food particles. During this breakdown, they release Vitamin K, vitamin B6, riboflavin and many other. Vitamin K is greatly absorbed into the bloodstream as the vitamin is an important clotting factor. Along with vitamins, many minerals and ions are too absorbed along with the water into the bloodstream. This maintains the ionic balance of the blood.
The anaerobic fermentation of the undigested carbohydrates and fatty acids produces lactic acid and other acids. These acids are strong enough to corrode the mucosa membrane due to the highly acidic medium in the colon. In order to neutralize the acidic medium, large intestine secretes alkaline juices into the lumen, thereby maintaining the pH.
