In each cavity of the body, there are 2 layers of tissue that lubricate and protect the organs. What is the main difference between these 2 layers?

The visceral layers are found on the surface of each organ while the parietal layer is found lining the cavity wall

What is the purpose of the serous membranes?

They line and enclose several body cavities (known as serous cavities) where they secrete a lubricating fluid which reduces friction from muscle movement
