Question

question 6 of 10
what is the best example of how the nervous system maintains homeostasis?
a. it makes muscles move.
b. it regulates breathing and heartbeats.
c. it allows the eyes and brain to communicate.
d. it receives physical sensations.

Explanation:

Homeostasis is the maintenance of a stable internal environment. The nervous system plays a crucial role in this. Breathing and heartbeats are essential physiological processes that need to be regulated to maintain homeostasis. The nervous system (specifically the autonomic nervous system) controls these involuntary functions. For example, if the body needs more oxygen (like during exercise), the nervous system can increase the breathing rate and heart - beat rate. Option A (making muscles move) is more related to motor function for movement rather than homeostasis. Option C (eye - brain communication) is mainly for sensory - perception and not directly for maintaining the body's internal stability. Option D (receiving physical sensations) is part of sensory input but not the best example of homeostasis maintenance compared to regulating vital functions like breathing and heartbeats.

Answer:

B. It regulates breathing and heartbeats.
