What two body systems control the reflex action?
Endocrine, and nervous.
The endocrine and nervous systems are a lot a like. They both control the rest of the body. The nervous system is the brain, and the spinal cord. That system thinks about things. Now, on the other hand, the endocrine system controls reflexes, and fast actions. This system also controls the hormones. It would mostly be the endocrine system.
