These lining cells are tall and thin, like columns in a building. They line your stomach and intestines and help soak up your food.

Columnar cells are taller than they are wide. They stand side by side like a row of columns.
Their nucleus usually sits near the bottom of the cell.
They line your stomach and your intestines, the long tubes your food travels through.
In your small intestine, the top of each tall cell is covered in tiny finger-like bumps called microvilli. They make a fuzzy edge that gives the cell lots more surface for soaking up food.
After your food is broken down into tiny bits, the tall cells in your intestine absorb them. That means they soak them up and pass them into your blood.
Some tall cells, called goblet cells, make slippery mucus. The mucus helps food slide along and protects the lining.
Press Soak up food on the 3D model, then press Make mucus.
