Why do organs look wet?

Question

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?

Answer 1

Yes, there’s a fluid called “interstitial fluid” that fills the gap between the cells. It’s incredibly important and its composition helps the cells absolve their functions.

26% of the water in your body forms the interstitial fluid, which is about 10-11 liters.
