The stomach serves first as a receptacle for swallowed food. Second, it begins the chemical digestion of the food by bathing the food in acid, turning it into kind of mush.
The small intestine is where the nutrients are absorbed from the food. Anything that is not absorbed into the bloodstream is considered waste and fiber. This is passed on to the large intestine where is is eventually eliminated.

What is the role of the pH levels in the stomach and small intestine in the process of digestion?
The pH levels in the stomach and small intestine play a crucial role in digestion. In the stomach, the acidic pH helps break down food and kill harmful bacteria. In the small intestine, the pH becomes more neutral to allow enzymes to work effectively in breaking down nutrients for absorption. Overall, maintaining the right pH levels is essential for proper digestion to occur.
What is the Ph of the small intestine?
Because it is the ideal pH for enzymes in intestine to work
Why does the enzyme pepsin present in the stomach denature in the intestine?
Pepsin has a optimum pH of 2, as found within the stomach. In the duodenum, the first part of the small intestine, the pH rises to 7.6. This relatively high pH damages the tertiary structure of the pepsin enzyme causing it to denature.
How is the proper pH for the functioning of the pancreatic-intestinal enzymes ensured?
The enzymes in the pancreas (which include several proteases, several nucleases, several elastases, pancreatic amylase, carboxypeptidase and steapsin) need to be of an alkaline pH (about pH8) to cancel out the highly acidic produce of the stomach. The pancreatic juices meet the bolus in the duodenum of the small intestine.
What are the changes in pH as food passes through your digestive system?
In the mouth, you have a pH of 7, in which amylase(the enzyme in saliva) works well with a pH near to 7. As you swallow the food, it gets passed into your stomach, which has a pH of 2. The low pH in the stomach helps digestion take place. Pepsin, the main enzyme in the stomach, works well with a pH of an acidic solution. Then the food gets passed into the small intestine. Here the pH is a slightly basic 8. The digestive fluids that surround the food, such as bicarbonate ion, work well in a slightly basic solution. The food has been split up into small enough molecules now and is ready to be passed absorbed into your bloodstream.

What is the difference between the fluids of the stomach and the small intestine?
fluids in the stomach are primarily acidic due to their low pH as caused by the presence of hydrochloric acid. fluids in the small intestines are basic that is they have high pH because of the high bicarbonate content from the bile secreted into the duodenum.
What is the pH of stomach and small intestine?
The pH of the stomach is typically around 1.5-3.5, due to the presence of hydrochloric acid that aids in digestion. In the small intestine, the pH is more neutral, ranging from 7 to 8, as digestive enzymes from the pancreas help break down food further.
Why are the differences in the pH of the mouth stomach and small intestine important for digestion?
The saliva need to be gentle enough at 7 pH to make foods small enough to swallow safely. The stomach needs to have strong acidity, at a 1 or 2 pH, to break down proteins into amino acids. The small intestine is where almost all of the absorption of the smaller portions are absorbed into the blood. The normal pH of the blood is close to 7 so the pH of the small intestine is 7.4.
How does the pH in the mouth stomach and the small intestine differ?
The pH in the mouth is around 6.5-7.5, slightly acidic due to bacteria and food breakdown. The stomach has a highly acidic pH of 1.5-3.5 to aid digestion. The small intestine has a pH of 7-8, which is more alkaline to neutralize the acidic chyme from the stomach and facilitate nutrient absorption.
When chyme moves from the stomach into the small intestine the pH increases from 1 to 7 What is the secretion that causes this increase in pH?
The secretion that causes the increase in pH when chyme moves from the stomach into the small intestine is bicarbonate, which is released by the pancreas. Bicarbonate helps to neutralize the acidic chyme from the stomach, creating a more favorable environment for digestion to continue in the small intestine.
What is the normal pH level in the small intestine?
its usually about 2-3 I believe the pH to be around pH 6-6.5 for the duodenum. The pH of the stomach is 1-3 so 2-3 is still in the stomach. The small intestine is anywhere between 6-8 as the pancreas dumps bicarbonate in.
Why is there food acid in the stomach and alkaline in the small intestine?
The acidic environment of the stomach helps break down foodstuffs that was ingested and also kills potential bacteria. The alkaline environment of the intestines facilitates the absorption of nutrients.
How is the pH of the stomach maintained?
Alkaline pancreatic juices are secreted into the small intestine and neutralize the acidic chyme.
Where is Ibuprofen absorbed in the stomach or intestine?
Ibuprofen is mostly absorbed in the duodenum (small intestine). It cannot be absorbed through the lining of the stomach due to its low solubility in water and the low pH of stomach acid (since ibuprofen dissolves in water better at higher pH's).
What alkaline is released into the small intestine?
Sodium bicarbonate is released into the small intestine to neutralize the acidic chyme coming from the stomach, creating a more optimal pH environment for digestion and absorption of nutrients in the small intestine.
