The heart of a pigeon and that of a frog are similar in that both are muscular and function to pump blood throughout the body, but they differ in structure and complexity. A pigeon, being a bird, has a four-chambered heart, which allows for efficient separation of oxygenated and deoxygenated blood. In contrast, a frog, an amphibian, has a three-chambered heart with two atria and one ventricle, which can lead to some mixing of blood. These differences reflect their evolutionary adaptations to their respective environments and lifestyles.
