The system involved in preparing our body in condition of stress and emergency:
Correct answer: C. Both nervous & endocrine system
- A. Nervous system only
- B. Endocrine system only
- C. Both nervous & endocrine system
- D. Both endocrine & exocrine
Explanation
The answer is both nervous and endocrine system. The nervous system is responsible for detecting danger and sending signals to the body to prepare for a fight-or-flight response. The endocrine system then releases hormones that help the body to respond to the stress. These hormones, such as adrenaline and cortisol, increase heart rate, blood pressure, and blood sugar levels. They also prepare the body for physical activity by increasing muscle strength and endurance.

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.
