How do ciliated protozoans obtain their food?

[Docscientist]

I read this in a website
"Paramecium has a cavity(gullet) that protrudes outside of the cell surface.The Co-ordinated movement of the rows of cilia causes the water laden with food to be steered into the gullet."
Can someone elaborate on that ?
