Interaction diagrams are used for capturing dynamic nature of a system. Sequence and collaboration diagrams are the interaction diagrams used for this purpose.
Sequence diagrams are used to capture time ordering of message flow and collaboration diagrams are used to understand the structural organization of the system. Generally a set of sequence and collaboration diagrams are used to model an entire system.
