Parrots possess a unique respiratory system characterized by lungs and air sacs, enabling efficient air passage and gas exchange. The trachea and bronchi direct air into the lungs, which connect to air sacs that extend into the body cavity, abdomen, and bones. During inspiration, air flows through the lungs into the air sacs, while exhalation reverses this process. This system provides continuous oxygen supply, supporting parrots’ flight activities and overall health.
