Yawning is a physiological behavior that involves deep inhalation, which increases the intake of oxygen and helps to regulate carbon dioxide levels in the blood. It may also play a role in cooling the brain and promoting alertness. Additionally, yawning can enhance lung function by stretching the respiratory muscles, thereby aiding in better ventilation. Overall, yawning serves as a mechanism to support respiratory efficiency and brain function.

Yawning involves the respiratory and nervous systems. The act of yawning helps to increase oxygen intake and regulate carbon dioxide levels in the body, while also serving as a trigger for changes in alertness and arousal controlled by the brain.
The respiratory system is the system that handles breathing.
The Respiratory System
The trachea is the airway in the respiratory system.
no, they do not have a respiratory system

how does the respiratory system work
1. Respiratory system 2. Cardiovascular system
The lungs are part of the respiratory system! they help the circulatory by giving oxygen, but they are just respiratory.
