Serous fluid

From Wikipedia, the free encyclopedia

In physiology, the term serous fluid is used for various bodily fluids that are typically pale yellow and transparent, and of a benign nature.

Saliva consists of mucus and serous fluid; the serous fluid contains the enzyme amylase important for the digestion of carbohydrates.

Another type of serous fluid is secreted by the serous membranes (or serosa), two layered membranes which line the body cavities. The serous fluid between the two layers acts as a lubricant and reduces friction from muscle movement.

A common trait of serous fluids is the ease in their role in assisting bodies in digestion, excretion, and respiration.
