Verified step by step guidance

Step 1: Understand the concept of serous membranes. Serous membranes are thin layers of tissue that line certain internal cavities of the body and cover the organs within these cavities. They secrete serous fluid to reduce friction between moving organs.

Step 2: Identify the organ in question. The problem specifies the heart, which is located in the thoracic cavity.

Step 3: Recall the specific serous membrane associated with the heart. The serous membrane surrounding the heart is called the pericardium. It consists of two layers: the visceral pericardium (directly covering the heart) and the parietal pericardium (lining the cavity).

Step 4: Differentiate between the other options provided. Meninges are membranes surrounding the brain and spinal cord, pleura surrounds the lungs, and peritoneum lines the abdominal cavity and covers abdominal organs. None of these are associated with the heart.

Step 5: Conclude that the correct serous membrane surrounding the heart is the pericardium, based on its anatomical location and function.
