Question

The regulation process of respiration functions through ________.

Answer 1

Signals:

1. Respiration is the process of breathing, which involves inhaling oxygen and exhaling carbon dioxide.
2. The chemoreceptors help in detecting signals which are transmitted between the brain and the lungs.
3. There is signal transmission between the medulla (sensitive to signals) and the respiratory muscles.
4. Thus, there is contraction and relaxation so that there is an exchange of gases (carbon dioxide and oxygen) and also to help the lungs to return to a normal state.

Final answer: The regulation process of respiration functions through signals.
