Birds (aves) have a four-chambered heart, which consists of two atria and two ventricles. This structure allows for efficient separation of oxygenated and deoxygenated blood, supporting their high metabolic needs and active lifestyles. The four chambers enable birds to maintain a high level of oxygen delivery to their tissues during flight.
