A. Remove waste products

B. Lower capillary pressure

C. Lubricate serous membranes

D. Nourish serous membranes

Step 1 of 2

Serous fluid:

The fluid present between serous membranes, that lines up pericardial, peritoneal, and pleural cavities is termed as serous fluid.

Serous fluid-Primary purpose

• Serous membrane contains two membranes namely, “parietal membrane”, which lines the cavity wall and “visceral membrane”, which covers the organs present within the cavity

• The primary function of serous fluid present between these two membranes is to provide lubrication between them

• Lubrication will avoid friction during the movement of enclosed organs

Therefore, the chief function of serous fluid is to “lubricate the serous membrane”. Hence, the correct answer is option.
