Why is it that when you see photos of surgery the stuff inside your body looks really wet?
Is it just from blood? Is there a fluid in our bodies that makes organs wet-looking? If there is a fluid, does it serve a purpose other than keeping organs wet?
In: Biology
Organs look wet because they are wet. The spaces between your insides are filled with fluid. This is called “interstitial fluid”. It keeps your insides from rubbing against each other or sticking together, and it also carries nutrients, hormones, waste, and other stuff to and from the cells all over your body. About a quarter of all the water in your body is interstitial fluid. It is very important!
