why is there a clear liquid coming from wounds
Serous exudate refers to thin, clear, watery, colorless to straw-colored fluid drainage from a wound. When you sustain a skin wound, the area becomes inflamed. Small blood vessels in the area leak fluid in response to this inflammation, which seeps from the surface of the wound as serous exudate. In addition to water, serous exudate contains proteins that promote blood clotting and scab formation.
