Verified step by step guidance

Understand the role of serous membranes: Serous membranes are thin tissues that line certain internal cavities of the body, producing a fluid that reduces friction from muscle movement.

Identify the location and function of each serous membrane: The pericardium surrounds the heart, the meninges cover the brain and spinal cord, the pleura covers the lungs, and the peritoneum lines the abdominal cavity.

Focus on the thoracic cavity: The thoracic cavity is the chamber of the body that is protected by the thoracic wall (rib cage and associated skin, muscle, and fascia). It contains the heart and lungs.

Determine which serous membrane is associated with the lungs: In the thoracic cavity, the lungs are covered by the pleura, a serous membrane that provides a smooth, frictionless surface for lung expansion and contraction.

Conclude that the pleura is the correct serous membrane covering the lungs in the thoracic cavity, as it specifically lines the lungs and the chest wall.
