Alkaline tide (mal del puerco) refers to a condition, normally encountered after eating a meal, where during the production of hydrochloric acid by the parietal cells in the stomach, the parietal cells secrete bicarbonate ions across their basolateral membranes and into the blood, causing a temporary increase in blood pH.
Because saliva is stimulated to flow more with the thought, sight or smell of food, or with chewing, pain and swelling will often get suddenly worse just before and during a meal ("peri-prandial"), and then slowly decrease after eating, this is termed meal time syndrome. However, calculi are not the only reasons that a salivary gland may become ...
Saliva, a liquid secreted by the salivary glands, contains salivary amylase, an enzyme which starts the digestion of starch in the food. [1] The saliva also contains mucus, which lubricates the food; the electrolyte hydrogencarbonate (HCO − 3), which provides the ideal conditions of pH for amylase to work; and other electrolytes (Na +, K ...
Saliva (containing the enzyme amylase) starts the digestion process. [3] [13] The food material is swallowed down the esophagus and then reaches the stomach, where digestion continues. The stomach is 15% of the total volume of the GI tract [3] and has a pH of 1-2 (which is very acidic). [2] Rabbits cannot vomit.
[17] [18] The normal pH range of saliva is between 6 and 7 and plaque biofilm is known to flourish in a pH between 6.7 and 8.3. [ 19 ] [ 20 ] This indicates that the natural environment of the mouth provided by saliva is ideal for the growth of bacteria in the dental plaque.
The lowest pH of the secreted acid is 0.8, [5] but the acid is diluted in the stomach lumen to a pH of between 1 and 3. There is a small continuous basal secretion of gastric acid between meals of usually less than 10 mEq/hour. [6] There are three phases in the secretion of gastric acid which increase the secretion rate in order to digest a ...
