latly; ive started to want to get into something medical wise once im finished with high schoo! But what does it take to be able to get into Anesthesiology or something along that kind of work!

One would need to go to medical school. The pre-med courses can include anatomy and physiology, biology, chemistry, organic chem, physics. Each program has different prereq's so need to check with individual program. After finishing med school, I believe that one must do their residency where they specialize. It's quite competitive to get into medical school, just fyi. Registered nurses with additional training may become a registered nurse anesthetist.
