Inside a blue whale, you'll find a massive and complex anatomy adapted for its size. Its heart is one of the largest of any animal, weighing about 400 pounds (180 kg) and pumping vast amounts of blood through its body. The lungs are also enormous, capable of holding around 5,000 liters of air, while the digestive system is lengthy, featuring a stomach with multiple compartments for processing food. Overall, the internal structure is designed to support its immense size and aquatic lifestyle.
