hospitals are health care institutions that provide patient treatment!
Yes, they sure are.  I wonder where the term "hospital" comes from?
that i dont know but the most common type is the general hospital which has an EMC department
Is that short for Emergency Medical Care?  
yes that is correct!
Lucky guess, lol.  Are there "non" general hospitals as well?
there are speciality hospitas!
What do speciality hospitals do?
