Parietal Cells

Parietal cells are specialized cells in the stomach lining that produce hydrochloric acid, which helps break down food and kill bacteria. They also release intrinsic factor, a protein necessary for absorbing vitamin B12. Located mainly in the stomach's lining, these cells play a crucial role in digestion and maintaining a healthy gut environment. Their activity is regulated by signals from the brain, stomach, and certain hormones, ensuring acid production occurs when food is present. Proper functioning of parietal cells is essential for efficient digestion and overall gastrointestinal health.
