Gastrointestinal Chart- Wikipedia

I had good news this morning as a result of an upper G.I. .  There are no abnormalities other than the hiatal hernia I have had for several years and half of  people over fifty have .  I also have had great results in the use of Nexia until the last couple of months when I have had morning heartburn.  My cardiologist referred me to my family doctor who referred me to Dr. Ransbottom for the upper GI.  There was a wonderful chart such as that below showing the system.  I was given samples of Dexalint pills to take in place of Nexium for the next couple of weeks.   I am relieved that it is nothing more serious than internal medicine can cure.

Upper gastrointestinal tract

Upper and Lower human gastrointestinal tractThe upper gastrointestinal tract consists of the oesophagus, stomach, and duodenum.[5] The exact demarcation between "upper" and "lower" can vary. Upon gross dissection, the duodenum may appear to be a unified organ, but it is often divided into two parts based upon function, arterial supply, or embryology.



[edit] Lower gastrointestinal tractThe lower gastrointestinal tract includes most of the small intestine and all of the large intestine.[6] According to some sources, it also includes the anus present in human body.[citation needed]



Bowel or intestine

Small intestine, which has three parts:

Duodenum - Here the digestive juices from pancreas (digestive enzymes) and gallbladder (bile) mix together. The digestive enzymes break down proteins and bile emulsifies fats into micelles. Duodenum contains Brunner's glands which produce bicarbonate and pancreatic juice contains bicarbonate to neutralize hydrochloric acid of stomach

Jejunum - It is the midsection of the intestine, connecting duodenum to ileum. Contain plicae circulares, and villi to increase surface area.

Ileum - It has villi, where all soluble molecules are absorbed into the blood (capillaries and lacteals).

Large intestine, which has three parts:

Cecum (the vermiform appendix is attached to the cecum).

Colon (ascending colon, transverse colon, descending colon and sigmoid flexure). The main function of colon is to absorb water, but it also contains bacteria that produce beneficial vitamins like Vitamin K.

Rectum in human body

Anus

The ligament of Treitz is sometimes used to divide the upper and lower GI tracts.[7]
