Explanation

**Step-by-Step Solution:**

1. **Identify the Command and Control System**: The question asks which part of the body acts as the command and control system. The primary candidate for this role is the brain.

2. **Understand the Role of the Brain**: The brain is considered the central information processing organ of the body. It is responsible for processing sensory information and coordinating responses.

3. **Functions of the Brain**: The brain controls both voluntary movements (like walking and talking) and involuntary functions (like heart rate and digestion). It also regulates essential bodily functions such as thermoregulation (temperature control), hunger, thirst, and circadian rhythms (sleep-wake cycles).

4. **Higher Cognitive Functions**: Beyond basic functions, the brain is involved in complex processes such as vision, hearing, speech, memory, intelligence, emotions, and thoughts.

5. **Conclusion**: Given its extensive control over both voluntary and involuntary functions, as well as its role in higher cognitive processes, the brain is rightly identified as the command and control system of the body.

**Final Answer**: The brain acts as the command and control system of the body.
