Question

Which other systems interact with the integumentary and nervous systems to regulate body temperature?


circulation


locomotion


sensation


respiration



Part B:



Which statement BEST supports the answer to Part A?




Involuntary muscle contraction is a function of the muscular system, and fluid secretion is a function of the digestive system.


Involuntary muscle contraction is a function of the digestive system, and fluid secretion is a function of the excretory system.


Blood vessel dilation is a function of the circulatory system, and involuntary muscle contraction is a function of the muscular system.


Blood vessel dilation is a function of the excretory system, and involuntary muscle contraction is a function of the circulatory system.

Answer 1

Part A: circulation and locomotion

Part B: Blood vessel dilation is a function of the circulatory system, and involuntary muscle contraction is a function of the muscular system. (Option 3)

Explanation: Temperature is regulated by vasodilation/vasoconstriction (circulatory) and shivering (involuntary muscle contraction — muscular/locomotor), coordinated by the nervous system and effectors in the integumentary system (sweating, heat loss).
