Visible Human, Coronal Section/Anterior Thorax
You selected: stomachThe stomach has three layers of smooth muscle which mechanically grind ingested food as hydrochloric acid (HCl) and enzymes such as pepsin break complex carbohydrates (sugars), fats and proteins into their componenets. Note the convoluted interior surface of the stomach. These ridges are reffered to as rugae.
An epithlielium lines the interior of the stomach (gastric epithelium). This epithelium contains many cell types, and is organized into units called gastric pits. Parietal cells secrete HCl while neck and surface mucus cells secrete mucus to protect the stomach from its own acid. Chief cells, located at the bottom of the gastric pits, secrete enzymes important in the breakdown of foodstuffs.
