Verified step by step guidance1
Understand the function of serous membranes: Serous membranes are thin layers of tissue that line certain internal cavities of the body, covering organs within these cavities.
Identify the primary role of serous membranes: The main function of serous membranes is to reduce friction between organs and surrounding structures. They achieve this by secreting a lubricating fluid called serous fluid.
Consider the options provided: Evaluate each option based on the known function of serous membranes.
Option analysis: 'To reduce friction between the organs and surrounding structures' aligns with the primary role of serous membranes. The other options do not match the primary function of serous membranes.
Conclude the analysis: Based on the understanding of serous membranes, the correct answer is the option that states their role in reducing friction.
