The correct Answer is:
### Step-by-Step Solution: 1. **Understanding the Pericardium**: The pericardium is a structure that surrounds the heart. It is important to know its composition and function. 2. **Composition of the Pericardium**: The pericardium is described as a double-walled membranous bag or fibrous sac. This means it has two layers: an outer fibrous layer and an inner serous layer. 3. **Function of the Pericardium**: The primary function of the pericardium is to keep the heart in a stable position within the mediastinum (the central compartment of the thoracic cavity). It also facilitates the movement of the heart and separates it from the lungs and other structures in the mediastinum. 4. **Evaluating Options**: The question likely provides multiple-choice answers. We need to evaluate each option based on our understanding of the pericardium: - **Option 1**: Double-walled membranous bag - This is correct. - **Option 2**: Single-walled - This is incorrect as the pericardium is double-walled. - **Option 3**: Double-walled cartilaginous cavity - This is incorrect; it is not a cartilaginous structure. - **Option 4**: Double-walled coelomic cavity - This is also incorrect; it is not a coelomic cavity. 5. **Conclusion**: Based on the evaluation of the options, the correct answer is that the pericardium is a double-walled membranous bag.
