Verified step by step guidance

Understand the concept of serous membranes: Serous membranes are thin tissues that line certain internal cavities of the body, forming a smooth, transparent, two-layered membrane lubricated by a fluid derived from serum.
Identify the layers of serous membranes: Serous membranes consist of two layers - the visceral layer, which covers the organs, and the parietal layer, which lines the cavity walls.
Differentiate between types of membranes: Recognize that synovial membranes line joint cavities, mucous membranes line body cavities that open to the exterior, and cutaneous membranes refer to the skin.
Focus on the peritoneum: The peritoneum is a specific type of serous membrane that lines the abdominal cavity and covers the abdominal organs, thus having both visceral and parietal layers.
Conclude that the peritoneum is the correct answer: Based on the characteristics of serous membranes and the specific function of the peritoneum, it is the membrane composed of both a visceral and parietal layer.
