The two organ systems that maintain homeostasis through their control of other organ systems are the and systems.

The two organ systems that maintain homeostasis through their control of other organ systems are the nervous system and the endocrine system.

1. Nervous System: This system uses electrical signals to communicate between different parts of the body rapidly. It detects changes in the internal and external environments, processes this information, and coordinates responses through a network of neurons.

2. Endocrine System: Unlike the nervous system, the endocrine system communicates through hormones, which are chemical messengers released into the bloodstream. These hormones regulate various functions, including metabolism, growth, and mood, and help maintain long-term homeostasis by affecting various organ systems over a longer duration.

Both systems work together to ensure that the body responds appropriately to maintain a stable internal environment despite external changes.
