If you remove a part of your internal body or organ, like a large tumor or kidney, what fills that gap they left?

Semirelated side question- if the air that entered the body cavity during surgery or in that open gap, does anything happen to it or do you just have a bubble of air in you now?

I can speak to the second question, the water in your body is pretty good at dissolving air. So small bubbles in the body just get absorbed into the bloodstream, and you eventually breathe it out. For example, the bends that divers get decompressing are caused by the dissolved air in the blood.
