Which of the following correctly describes the function of serous fluid?
A
It facilitates the exchange of gases between the blood and tissues.
B
It provides nutrients to the epithelial cells of serous membranes.
C
It acts as a barrier to prevent infection in the body cavities.
D
It reduces friction between the parietal and visceral layers of serous membranes.
Verified step by step guidance1
Understand the role of serous membranes: Serous membranes line and enclose several body cavities, where they secrete a lubricating fluid called serous fluid.
Identify the location of serous membranes: These membranes are found in the thoracic and abdominal cavities, covering organs such as the heart (pericardium), lungs (pleura), and abdominal organs (peritoneum).
Recognize the composition of serous fluid: Serous fluid is a thin, watery fluid that is secreted by the cells of the serous membranes.
Determine the function of serous fluid: The primary function of serous fluid is to reduce friction between the parietal and visceral layers of the serous membranes as organs move or expand, such as during breathing or digestion.
Eliminate incorrect options: The other options describe functions not related to serous fluid, such as gas exchange, nutrient provision, or infection prevention, which are not the primary roles of serous fluid.
