Answer:
c. immune functions.
Explanation:
The endocrine system is involved in the regulation of metabolic rate, body temperature (thermoregulation), tissue development and labor contractions except immune functions.
Studies have shown that no hormone has been identified as being important in the regulation of the immune system. Therefore immune functions is not a regulatory function of the endocrine system.
Although, there have been articles on the endocrine and immune system crosstalk, only a hypothesis of various proteohormones not single hormones have been discovered to act on immunocompetent cells.
