What quality is typical of serous fluid?

Serous fluid is typically characterized by its clear, pale yellow appearance and a consistency that can be compared to that of egg whites. This comparison is significant because it indicates the fluid's composition, which is generally serous fluid found in anatomical spaces such as the pleural, peritoneal, or pericardial cavities. The usual clarity and low cellularity of serous fluid distinguish it from other types of bodily fluids that might be thicker or more opaque.

This egg white consistency reflects the fluid's relatively low viscosity and the presence of proteins, which can contribute to a more gel-like texture without being as thick as mucus. In contrast, higher viscosity would not align with the characteristics of typical serous fluid.
