The main mechanism that can cause loss of fluid in the body would be from sweating and from urinating. Pathological causes that might cause loss of body fluid like diarrhea and bleeding.
Drugs that induce sweating is called diaphoresis. Drugs that induce urine production called diuretic.
If the question is ask for the name of condition where the body loses fluid it can be dehydrated or shock(more severe than dehydrated).
It's important to take your time in any game that requires focus, strategy, and quick thinking - while you have to be in physical shape for baseball, you also have to have the mental capacity to be aware of every thing around you and look for the perfect opportunity to make any move so that you can make the best possible move.
Examples: (Hitting the ball at the perfect time with the right amount of force, knowing when it's safe to run home or if you need to stop at what ever base, being aware of where the ball is at all times, knowing where/who to throw the ball to when you want to get someone out, knowing how to pitch the ball to trick the batter.)
The correct answer is Cortisol.
Hope this helps.
