Parietal serosa lines which part of a body cavity?

Explanation:
Parietal serosa line the walls of body cavities. Serous membranes have two layers: a parietal layer that attaches to the cavity wall and a visceral layer that covers the organs inside the cavity, with a small fluid-filled space between them to reduce friction. So, the parietal serosa lines the cavity walls, while the organs are covered by the visceral serosa. Blood vessels and nerves aren’t lined by a serous membrane.
