Correct Answer: (2) Homeostasis
Homeostasis is the maintenance of a constant environment (i.e. temperature, water levels, glucose concentrations) in the body. Example of this is vasodilation wherein the capillaries expand to bring blood closer to the surface of the skin to cope up with the increase of temperature brought about by strenuous exercise.
Synthesis, excretion, and locomotion are not the reasons why vasodilation occurs.
