Which system carries messages quickly in the body?
Answer and explanation
Correct answer: Nervous system
The nervous system provides rapid control and communication in the body. Neurons receive information and transmit electrical impulses along nerve fibres; chemical signals then pass across synapses. This allows quick responses such as withdrawing a hand from a hot object. Therefore option A, the nervous system, is correct. The digestive and respiratory systems perform processing and gas exchange, while the skeletal system mainly provides support and protection, so none of those is the primary rapid messaging system.
