Transcript of Acids and Bases: The Digestive System

Digestion is a process of breaking down food so they can be absorbed by our body easily. Digestion can be divided into types such as mechanical and chemical break down. Mechanical is the forms of physical break down, Chemical is a form that uses enzymes.
Acids and Bases: The Digestive System
i know that you heard that our stomach acid Gastric acid is a digestive fluid, formed in the stomach. It is composed of hydrochloric acid (HCl) (around 0.5%, or 5000 parts per million) as high as 0.1 M, potassium chloride (KCl) and sodium chloride (NaCl), will be able to melt a razor blade. the mucus keeps the acids inside the organ from damaging any others, it's when it fails to do that we have a SITUATION called Ulcer.
The Chemical formula
Generally the stomach acid is good for us because if we don't have that our body would be struggling to absorb nutrients and vitamins from the large quantity of food. however if the acids escapes for some reason it could be extremely as it can eat through our stomach. that's why we need to eat healthy food in correct time.

Generally our body has an pH level of 7 to 7.4.
in order for us to digest our food, proper gas exchange, hormones secretions and many it requires a form of acid or base.
When the food enters your stomach, it encounters the highly acidic pH of 1.3. Due in large part to the secretion of hydrochloric acid, the change in pH enables the dismantling of food. The stomach churns the food into chyme and kills unwanted germs in preparation for the small intestine. At the first section of the small intestine, the chyme enters your duodenum, which has a pH of 6 to 6.5. The acidity level begins to descend as the pH value rises.
The intestines do not need a highly acidic terrain as does the stomach, because, it doesn't need it. Its job is absorbing vitamins and minerals. Once the small intestine absorbs the important nutrients, the chyme propels along by peristalsis, muscular contractions, to the large intestine. Upon entering the large intestine, there is a change in pH to 5.5 to 7. Very little absorption takes place there. The bowel prepares to evacuate the leftover waste from the body.
we have many organs with different tasks, for them to function their own tasks, there is different way of doing things. Like Tom and Jerry different but same. i am confusing you? well then forget the analogy and move on. Therefore they all have different pH level such like bile it secretes acid way strong than our mouth. get it? yeah, good.
HCl + H2O → H3O+ + Cl−
