Birds have a unique respiratory system that enhances their breathing efficiency, especially during flight. They possess air sacs that allow for a continuous flow of air through their lungs. When a bird inhales, fresh air enters both the lungs and the air sacs simultaneously, ensuring a constant availability of oxygen. Their small, rigid lungs help extract more oxygen from each breath, which is crucial for their active lifestyles, particularly at high altitudes.
Birds have a unique respiratory system that helps them breathe efficiently, especially when flying. Unlike humans, birds have air sacs that allow air to flow through their lungs in a continuous loop. When a bird inhales, air goes into the lungs and the air sacs at the same time. This means that fresh air is always available for the bird, even when it exhales. The lungs are small and rigid, which helps birds get more oxygen from each breath. This special system is important because birds need a lot of oxygen to support their active lifestyles, especially when they are flying high in the sky (make it shorter)
