receiving and processing stimuli from the body
The correct answer is: receiving and processing stimuli from the body.
To determine the correct answer, we need to understand the functions of the nervous system. The nervous system is a complex network of neurons that allows for communication and coordination throughout the body. It consists of the central nervous system (brain and spinal cord) and the peripheral nervous system (nerves that connect the central nervous system to the rest of the body).
1. Option A: Exchanging gases between the body and the environment: This function is mainly performed by the respiratory system, which includes the lungs and the process of breathing.
2. Option B: Breaking down food and extracting nutrients: This function is primarily carried out by the digestive system, where food undergoes mechanical and chemical breakdown and nutrients are absorbed into the bloodstream.
3. Option C: Receiving and processing stimuli from the body: This is a correct description of one of the main functions of the nervous system. It detects stimuli from both the external environment (such as touch, sight, and sound) and internal body conditions. The information is then processed and transmitted to appropriate parts of the body, enabling us to respond and react to our surroundings.
4. Option D: Defending against disease like the flu or common cold: This function is primarily associated with the immune system, which is responsible for detecting and eliminating pathogens. The nervous system does not play a direct role in defending against disease.
Based on the above analysis, the correct answer is option C: receiving and processing stimuli from the body.
