The heart is one of the vital organs and is functionalized for blood circulation from its early development. Some vertebrates have altered their living environment from aquatic to terrestrial life over the course of evolution and obtained circulatory systems well adapted to their lifestyles. The morphology of the heart has been changed together with the acquisition of a sophisticated respiratory organ, the lung. Adaptation to a terrestrial environment requires the coordination of heart and lung development due to the intake of oxygen from the air and the production of the large amount of energy needed for terrestrial life. Therefore, vertebrates developed pulmonary circulation and a septated heart (four‐chambered heart) with venous and arterial blood completely separated. In this review, we summarize how vertebrates change the structures and functions of their circulatory systems according to environmental changes.
