Is Your Stomach Acid (Gastric Acid) Diluted When You Drink Water?

The video explains the role of gastric acid in digestion, detailing its composition and production. It covers the pH scale, emphasizing the stomach's acidity levels and how they change with food and water intake. The stomach's buffering capacity and self-regulation mechanisms are also discussed, highlighting how it maintains optimal acidity levels.

What are the main components of gastric acid?

• Hydrochloric acid, sodium chloride, and potassium chloride

• Sulfuric acid, sodium bicarbonate, and calcium chloride

• Hydrochloric acid, magnesium sulfate, and sodium chloride

• Acetic acid, sodium chloride, and potassium sulfate

What is the typical pH range of the human stomach?

• 5 to 7

• 7 to 9

• 1 to 3

• 4 to 6

How does the pH of the stomach change after eating?

• It decreases to 1

• It remains constant

• It increases to about 4 or 5

• It increases to 7

What is the role of buffering molecules in the stomach?

• They increase the production of gastric acid

• They ensure minimal variation in stomach pH

• They convert pepsinogen into pepsin

• They neutralize all stomach acids

What happens when you drink a liter of water in terms of stomach acidity?

• The stomach acidity increases permanently

• The stomach pH remains unchanged

• The stomach becomes less acidic temporarily

• The stomach becomes more acidic permanently
