The way I look at it the body has 6 parts: Legs, abs/obliques, chest, shoulders, arms and back.
It would be pretty hard to work all the muscles in all the parts in one day. I only work one part on a day, and routines are 90 mins to two hours long. That's a 6 day per week routine so it's probably not what most people would do, but if you combine 2 sections on any one day then you train the whole body in 3 days a week. I'd allow a couple of hours to get through each routine.
One girl I like on you tube is Carly Rowena. This one is a good for back with a bit of arms throw in.

The one I like best for learning anatomy is 'Built by science'. These videos explain the body and how muscles and joints work together.

Boom!
