Final answer:
The nervous system helps maintain homeostasis in dogs by regulating various bodily functions.
Step-by-step explanation:
The relationship between the nervous system and homeostasis in dogs is that the nervous system helps maintain homeostasis in dogs. Homeostasis is the balance of internal conditions that allows an organism to function properly. In the case of dogs, the nervous system plays a crucial role in regulating various bodily functions, such as body temperature, heart rate, and digestion, which are necessary for maintaining homeostasis.
For example, the autonomic nervous system, which is part of the nervous system, regulates internal organs and glands in dogs. It consists of the sympathetic division (fight-or-flight response) and the parasympathetic division (rest and digest). These divisions work together to maintain homeostasis by controlling heart rate, digestion, and other functions.
Therefore, option 1) The nervous system helps maintain homeostasis in dogs is the correct answer.
