Family From a systems perspective. n family is detined as a collection of people who are inte!!,nilcd, i11t1r:wti11g and intt. !nlependent (Thmt, 1997:126).,Just like other systems, the parts (family mcmher. s) interact with e. 1ch other and the action of one affects t J1c other members. The family has a boundary which. means thatotherp eoplecon recognize its m P. mbers and those who arc not. In fact a person may be identified primarily ns a member of a particular family. 18 There have heen many cl1a11ges in the social coote11. 1: of the Fi Jipino family and these may have modified how it performs its healtb tasks and its capacity to re1nain as the prim,u-y source of support to its members.
