The stomach is protected from the hydrochloric acid by
epithelial cells, which secrete a bicarbonate substance that covers the mucosa.
Since the bicarbonate solution is alkaline, it neutralizes the hydrochloric

Importantly, the consistent secretion of the bicarbonate solution is what
protects the stomach from the strong acidic environment.
