Consider Option C: Circulatory and integumentary systems

  • Reduced blood volume affects circulation first, while sweating mechanism (integumentary system) is directly impacted.

Other Options:

  • A is incorrect: Secondary systems affected as dehydration progresses
  • B is incorrect: Affected after circulatory changes occur
  • D is incorrect: Impacted in later stages of severe dehydration
