Digestion



Chemical digestion occurs once food has





entered the stomach from the esophagus.










Most people believe that the stomach's function is digestion. The true function of the stomach is to store food, the stomach makes it possible for us to eat meals through out the day. The stomach also disinfect anything that is not suppose to come down with the food. HCl make the disinfection possible, with a ph of 2 it kills bacteria and begins to break apart food.








The enzyme that digests protein is called pepsin

Luckily we have mucus that is secreted to protect

our stomach lining. If we didn't then the pepsin would digest our stomachs since the stomach is made out of protein.





A Gastric ulcer is when ones stomach begins to digest itself. Gastric Ulcers are caused by a bacterial infection known as Helicobacter Pylori. Gastric Ulcers are cured with weeks of antibiotics.


While all of this is occuring the food
stays put in the stomach due to 2
sphincters. One is called the cardiac sphincter
which keeps the food from going up.
The 2nd is called the pyloric sphincter which keeps the food from going down.


The liver is responsible for the production of bile.
Bile is a chemical made from dead red blood cells.
Bile breaks down the fats that we eat.
After bile is produced it is stored in the gall bladder, it is released in the presence of fats in order to break them down.

In your blog you mention the gastric ulseras, before presenting my case on this topic, I felictarte because the information is very comprehensive and helps people to clarify the true functions of different organs. More than a year ago I was suffering from a gastric ulsera, suffered discomfort for a long time, take antibiotics for three consecutive months, the results were positive but not those I expected, and I went to the doctor suggested I use generic viagra, it was like a holy remedy , In a matter of two weeks as my ulcer disappearances and extra also improved my sexual life, but hey this is beside the topic of your blog. For me it is very functional all that makes the stomach and all organs related to digestive system.
