The pyloroplasty component of the operation was designed to counter a serious side effect of vagotomy, namely paralysis of the pyloric sphincter, which prevented the release of stomach contents into the small intestine. (The pyloric sphincter is the last outpost of central control of ...
In contrast, the pH of stomach acid ranges from 1.5 to 3.5, making it acidic. A low pH is helpful for digestion and for eliminating any bacteria that enter the stomach. The pH of biological fluids, organs, and other parts of the body can affect the biochemical processes that support ...
What is the normal pH of urine? Describe two factors that can affect urine pH. Why is it necessary for the stomach contents to be so acidic? Why is water so important to living organisms? Most culture media must have a neutral pH (~7.0). Why is this the case? Clue: What conditions...

However, there are enzymes that work in acidic compartments of living things, such as the lysosome of cells or inside the stomach, and work better at an acidic pH. What does optimum pH mean? Optimum pH is the pH value at which an enzyme can work best. Most enzymes in living things ...
We know that our stomach contains hydrochloric acid which helps in the digestion of food. When the stomach produces too much of hydrochloric acid during indigestion, we feel a lot of pain and irritation. Hence, we generally use antacids or a mild base which increases the pH of the acidic ...

Anaerobic ciliates also live as endocommensals in the enlarged forestomach (rumen) of ruminants and in the cecum of other mammals with postgastric fermentation. It is unlikely that any of these ciliates (e.g., in the genera Dasytricha, Entodinium, and Polyplaston) are capable of a free-li...
The onset is characterized by loss of appetite, watery diarrhea, dehydration, hypothermia, weight loss, and depression. Younger poults may die. The duodenum and jejunum are pale and flaccid, and the ceca filled with frothy, watery contents. The feces may be green to brown, watery, and may ...
