Visceral serosa covers which structure?

Visceral serosa covers which structure?

• A. The organs in the cavity
• B. The cavity walls
• C. The bones
• D. The skin

Answer: (A)

Visceral serosa are the membranes that cling to the surfaces of internal organs within a body cavity, providing a smooth, slippery covering that reduces friction as organs move. This layer lines the organs themselves, such as the stomach, intestines, liver, and the heart’s outer surface, depending on the cavity. The opposing layer, the parietal serosa, lines the walls of the cavity. For example, the visceral pleura covers the lungs, the visceral peritoneum covers abdominal organs, and the visceral pericardium covers the heart. Because of this setup, the correct understanding is that visceral serosa cover the organs in the cavity, not the cavity walls, bones, or skin.
