The lowest pH of the secreted acid is 0.8, [7] 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. [8] There are three phases in the secretion of gastric acid which increase the secretion rate in order to digest a ...
Metabolic alkalosis is an acid-base disorder in which the pH of tissue is elevated beyond the normal range (7.35–7.45). This is the result of decreased hydrogen ion concentration, leading to increased bicarbonate (HCO − 3), or alternatively a direct result of increased bicarbonate concentrations.
Pulmonary aspiration is the entry of solid or liquid material such as pharyngeal secretions, food, drink, or stomach contents from the oropharynx or gastrointestinal tract, into the trachea and lungs. [1] When pulmonary aspiration occurs during eating and drinking, the aspirated material is often colloquially referred to as "going down the ...
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.

Hypertonic salt water—being more concentrated than human blood—creates an osmotic gradient when it enters the lungs. This gradient draws water out of surrounding lung tissues into the alveoli and bronchioles, leading to irritation and inflammation. Salt water can also cause oxidative stress, dilution of pulmonary surfactant, breakdown of ...
Whether the spice they seek is fiery or acidic and sour, humans can be drawn to the perceived danger of extreme foods. Eating sour or spicy foods is more about your brain than palate, scientists ...
Research has suggested that self-evaluation of halitosis is not easy because of preconceived notions of how bad we think it should be. Some people assume that they have bad breath because of bad taste (metallic, sour, fecal, etc.), however bad taste is considered a poor indicator. Patients often self-diagnose by asking a close friend. [21]
