What is the meaning of the verb "lines" in this context?

"Epithelial tissue covers body surfaces, lines body cavities and form glands"

I searched in the dictionary but I found a lot of results and I'm not sure which one is matched.

  • $\begingroup$ (transitive) To cover the inner surface of (something), originally especially with linen. $\endgroup$
