What are the impacts that are caused by zero gravity?

I need/want to know some of the impacts that are caused by zero gravity on human body.
I especially need impacts on lung (respiratory system) and heart (circulatory system).
To be more detailed:
1) What happens to lung and heart when in space.
2) What is the reason that question 1 is happening
And any other impacts.

Thank you

How are viruses harvested from a tissue culture?

This was one of the question for my microbiology review and im having a hard time finding an answer, does this have anything specifically to do with the entry and exit portals such as the respiratory system, and it’s excrements such as mucous? How in general are virus samples collected from body or tissue samples?
Any help would be greatly appreciated thanks!
