Verified step by step guidance

Step 1: Understand the question by identifying the key terms. The question asks for the name of the double-walled serous membrane that encloses each lung. Key terms include 'double-walled serous membrane' and 'lung.'
Step 2: Recall the anatomy of serous membranes. Serous membranes are thin, double-layered structures that line certain cavities and organs, providing lubrication to reduce friction during organ movement.
Step 3: Review the specific serous membranes in the body. The peritoneum lines the abdominal cavity, the meninges surround the brain and spinal cord, the pericardium encloses the heart, and the pleura surrounds the lungs.
Step 4: Focus on the lungs. The pleura is the serous membrane specifically associated with the lungs. It consists of two layers: the visceral pleura (attached to the lung surface) and the parietal pleura (lining the thoracic cavity). Between these layers is the pleural cavity, which contains serous fluid.
Step 5: Confirm the correct answer. Based on the anatomical relationship, the term that refers to the double-walled serous membrane enclosing each lung is 'pleura.'
