Combining data from 2 worksheets

I have 2 worksheets that I am working with. They have very similiar information, but what I would like to do is combine them. The common factor is the account number. I'd like to know if there is a way to bring all of the information from one worksheet and combine it with the second worksheet, matching them up by the column called, "Account". That is the only data that they have in common. Can someone help me with this?
