The system involved in preparing our body in a state of stress and emergency:
Correct answer: C. Both the nervous & endocrine systems
- A. Nervous system only
- B. Endocrine system only
- C. Both the nervous & endocrine systems
- D. Both endocrine & exocrine
Explanation
During stress or emergency situations, both the nervous system (especially the sympathetic division of the autonomic nervous system) and the endocrine system (particularly the adrenal glands) work together to prepare the body for "fight or flight." The nervous system quickly sends signals to activate organs and muscles. The endocrine system releases hormones like adrenaline (epinephrine) and cortisol to maintain the response.

About Coordination and Control
Coordination depends on receptors, neurons, synapses and nerve impulses, with reflex actions traced through the reflex arc and the roles of major brain regions. Chemical coordination covers endocrine glands and hormones, including how hormones regulate growth, metabolism, reproduction and internal balance, unlike rapid nervous control.
