What creates a family system?

Families are created and maintained by the interactions between its members. These interactions involve interdependency and balance between each member's needs and roles within the family. While rules and punishments, financial support, and external influences may all play a role in shaping a family, they are not the primary factors in creating a family system. Instead, it is the dynamic relationships and interactions between family members that form the foundation of a family system. So, while these other options may be important aspects within a family, they are not what ultimately creates a family system.
