What does the beluga whale's circulatory system do?

The beluga whale's circulatory system is adapted to efficiently support its life in cold marine environments. It features a robust heart and a network of blood vessels that help regulate body temperature by directing warm blood to vital organs while allowing cooler blood to circulate in peripheral areas. This system also aids in oxygen storage and utilization, enabling belugas to dive for extended periods. Overall, their circulatory system plays a crucial role in maintaining homeostasis and supporting their active lifestyle in the ocean.
