Inside each kidney filter, tiny blood vessels loop around and around. Mesangial cells sit in between, holding them up and keeping things clean.
Drag to turn it around. Use the buttons to zoom in and try things from the lessons.

Each kidney filter is a little ball of looping blood vessels called a glomerulus.
Mesangial cells sit right in the middle, between the loops. They have a body with a few arms that reach out and touch the blood vessels.
Mesangial cells are a bit like the stems of a bunch of grapes. They hold all the loops together in one bunch.
A clean filter means your kidneys can keep your blood clean too.
Press Clean up on the 3D model and watch the stuck bits disappear.
