A sequence generates a series of sequence_item’s and sends it to the driver via sequencer. Thus, body() method of a sequence defines sequence_item’s that will be used.
On the other hand, a sequence item is the basic transaction used by the driver to drive the interface.
The following picture from UVM Basics tutorial explains it fully:
