Which organ controls body function and synthesizes information?

• A. Brain
• B. Stomach
• C. Pancreas
• D. Skin

Answer: (A)

The brain acts as the command center, processing information from senses and directing how the body responds. It takes in signals via nerves, interprets them, stores experiences, and sends coordinated instructions to muscles and glands. This is why it both controls body function and synthesizes information—turning raw sensory input into organized action plans and decisions.

The stomach is mainly responsible for digestion—breaking down food and absorbing nutrients. The pancreas produces digestive enzymes and hormones that regulate metabolism, but it doesn’t coordinate overall body functions. The skin protects the body and provides sensory input, yet it does not integrate and direct bodily processes to the level the brain does.
