What term refers to one's relatives in the context of blood relations?

The term that refers to one's relatives in the context of blood relations is "kin." It encompasses family members and can denote a variety of relationships, including immediate family like parents and siblings, as well as more distant relatives such as cousins, aunts, and uncles. In many cultures, the concept of "kin" is significant as it reflects familial connections, heritage, and lineage.

The other terms mentioned have different meanings. "Kriah" refers to a Jewish practice of mourning involving tearing one's clothing, "kever" translates to grave or tomb, and "levaya" refers to the funeral procession. None of these terms connote blood relations or familial connections in the way that "kin" does.
