Colon Info

The large intestine is a sausage-like, wider and shorter than the small intestine. It is typically divided into cecum, colon, and rectum, and concerned especially with the resorption of water and the formation of feces. The colon is inferior to the stomach and superior to the anus. The large intestine is located in a more dorsal position than the abs. It is in a proximal position located toward the center of the body.


The colon is part of the large intestine, the final part of the digestive system. Its function is to reabsorb fluids and process waste products from the body and prepare for its elimination. The colon consists of four parts.

While the small intestine plays a major role in absorbing nutrients from food, the large intestine plays a much smaller role. It stores waste, reclaims water, maintains water balance, absorbs certain vitamins , and provides for flora-aided (mostly bacterial) fermentation.

Aid to the Digestive System

The major job of the large intestine is to absorb water from the remaining indigestible food matter and transmit the useless waste material from the body. This helps make the food easier to digest. By getting rid of the excess materials in the body the large intestine acts as an exit or trash release to help cleanse the body.

The Four Major Parts Of The Large Intestine

Independent Large Intestine

Unlike other parts of the digestive system, the large intestine does not contain enzymes or mucus. It does not contain any folds or villi opposed to the small intestine that does contain these structures.

Stomach Ulcers


  • dull pain in the stomach
  • weight loss
  • not wanting to eat because of pain
  • nausea or vomiting
  • bloating
  • burping or acid reflux
  • heartburn (burning sensation in the chest)
  • pain improves when you eat, drink, or take antacids


  • an infection with the bacterium H. Pylori
  • long-term use of nonsteroidal anti-inflammatory drugs (NSAIDs), such as aspirin and ibuprofen
  • excess acid (hyperacidity) in the stomach, which may be related to genetics, lifestyle (stress, smoking), and certain foods
  • Zollinger-Ellison syndrome, a rare disease that makes the body produce excess stomach acid
  • Smoking
  • Excessive consumption of alcohol


Stomach ulcers are painful sores that can be found in the stomach lining or small intestine. Stomach ulcers are the most visible sign of peptic ulcer disease. They occur when the thick layer of mucus that protects your stomach from digestive juices is reduced, thus enabling the digestive acids to eat away at the lining tissues of the stomach.

Stomach ulcers are easily cured, but they can become severe without proper treatment.


Treatment will depend on the cause of the ulcer. Most ulcers can be treated with a prescription of a doctor. It’s important to promptly treat an ulcer. If you have an actively bleeding ulcer, you’ll likely be hospitalized for intensive treatment with IV ulcer medications, and may also require blood transfusion.
