Gallbladder epithelial cell
Make it clearer
A gallbladder epithelial cell is part of the simple columnar epithelium of the mucosa, the organ's inner lining. Its surface has many microvilli, which are tiny projections. Picture an edge covered with countless fine bristles.
These cells absorb water from bile and move it toward the surrounding tissue. Removing water concentrates the bile left in the gallbladder. This is a shared task of the epithelium, not the isolated work of a single protein.
In brief
The gallbladder mucosa is lined by simple columnar epithelial cells with abundant microvilli, small projections from the cell surface.
These cells absorb water from bile and transport it toward the surrounding tissue, leaving the bile that remains in the gallbladder more concentrated. This is coordinated work by the epithelium, not the action of a single protein.
