Your stomach is full of strong acid, so why doesn't it melt itself? Foveolar cells cover it in a thick blanket of slime.
Drag to turn it around. Use the buttons to zoom in and try things from the lessons.
The 3D model can't load right now. Check your internet connection, or try a different web browser.
Foveolar cells line the inside surface of your stomach and the tiny pits that dip down into it. They stand side by side like tall columns.
The top of each cell is filled with a big pale cup of mucus. Mucus is thick slime.
The cells on your stomach surface wear out fast. Your body replaces them every few days!
Your stomach makes acid strong enough to help break down food. Foveolar cells protect the stomach wall from it.
Scroll up to the 3D model and press Make slime to see the shield cover the cells.
