What's in between my organs?

We're full of blood, yes, but it's all contained in one area or another. I know we can't be dry in there, it's gotta be slippery so we can move around. Is it just, mucous or slime or whatever?

It depends on the organs you're talking about. There is usually just a sterile fluid that acts as a lubricant between different organs so they can rub together and not cause irritation. There's also connective tissue between some organs which is exactly what it sounds like and basically helps everything stay in the right shape.
