Large animals have developed specialized respiratory systems that often include lungs with extensive surface areas to facilitate efficient gas exchange. Many also possess a robust circulatory system that includes a strong heart and a network of blood vessels to transport oxygen quickly to tissues. Additionally, some large animals have adaptations such as increased hemoglobin concentrations in their blood or specialized respiratory structures, like air sacs in birds, to enhance oxygen uptake and delivery. These adaptations collectively ensure that their oxygen requirements are met effectively.
