Moving multiple columns (8 x sets of 3) with data in separate rows into 3 columns

Hello
I have data that are in multiple columns in 8 sets of 3 columns, with data in separate rows. I would like to combine the columns, so I end up with 3 columns. All of the headings are different except, the first of a set always contains "Body", the second "Feet", the third "Head". How do I combine the columns?
