Footings are the concrete filled trenches (load bearing), foundations are the cinder block or brick or poured walls that transfer the loads from above to the footings.

Often you hear it refered to as "pouring the foundations" as it is just part of the overall process of getting the house "out of the ground". Technically though the foundations are just that...."the foundations" of the building, all that is structurally holding the building up.

Monolithic slabs are a little different as the slab and footer ae all poured as one the slab then is part of the foundation.
