Question

Quizplus · Accepted Answer

The nervous system is responsible for responding quickly to environmental stimuli, transmitting signals between the brain and different parts of the body at high speeds. The immune and lymphatic systems respond more slowly, as they involve the production and transport of cells and other components to fight off infections or foreign substances. While the muscular system can contract rapidly, it relies on signals from the nervous system to do so. Therefore, the nervous system is the best choice for the system that responds fastest to environmental stimuli.
