Respiratory System . ;)
your nose!
When a bird inhales, air first enters through the nostrils located at the base of its beak. The nostrils lead to the bird's respiratory system, where the air is then taken in through the trachea into the lungs for the exchange of gases to occur.
Oxygen first enters your body through your respiratory system, specifically through your nose or mouth, where it is inhaled into your lungs. In the lungs, oxygen is transferred from the air you breathe into your bloodstream to be circulated throughout your body to provide energy to your cells.
The tonsils are the first lymphatic tissue that inspired air encounters as it passes through the mouth and nose. The tonsils help to trap and remove pathogens and foreign particles in the air as it enters the respiratory system.

Yes, the nose is the first part of the respiratory system that cleans, moistens, and warms the air we breathe. It is lined with hair and mucus that trap particles, and blood vessels and mucous membranes that humidify and warm the air before it reaches the lungs.
