The blue whale's heart is enormous—about the size of a small car—because it needs to pump a massive volume of blood throughout its large body, which can weigh up to 200 tons. This large heart ensures that oxygen and nutrients are efficiently delivered to all its organs and tissues, supporting its immense size and energy requirements. Additionally, the heart must generate enough pressure to circulate blood through the whale's extensive circulatory system, including its deep-sea dives.
