acid secretion

Acid secretion in the stomach involves specialized cells called parietal cells that produce hydrochloric acid. This acid helps break down food, especially proteins, and activates digestive enzymes. When you eat, signals trigger these cells to release acid into the stomach. The body carefully controls acid levels to digest efficiently while protecting the stomach lining from damage. This process is essential for proper digestion and nutrient absorption, and it is regulated by nervous and hormonal signals to balance acid production according to food intake.
