Quizplus · Accepted Answer

The integration of body functions is controlled by both the nervous system and the endocrine system. The nervous system controls rapid and specific responses to changing conditions, while the endocrine system controls slow, but long-lasting responses to maintain homeostasis. Together, these two systems work to coordinate and regulate all bodily functions. The respiratory system is responsible for gas exchange, the immune system defends against pathogens, but they do not play major roles in integrating body functions.
