A _______ Lines a Body Cavity That Does Not Open

Question

A _______ lines a body cavity that does not open to the outside of the body.
A) mucosa
B) serous membrane
C) synovial
D) connective tissue membrane

Accepted Answer

A serous membrane lines body cavities that do not open to the outside of the body and secretes a lubricating fluid to reduce friction between organs and body cavity walls. Mucosa lines body cavities and tubes that open to the outside of the body, synovial membranes line joint cavities, and connective tissue membranes cover and protect organs.
