The organs of a Tyrannosaurus rex were proportionate to its massive size, with estimates suggesting its heart could weigh around 400 pounds and its lungs resembling those of a large modern bird. The stomach was also substantial, capable of holding large quantities of food to support its carnivorous diet. Overall, the organ sizes of T. rex were adapted to its predatory lifestyle and large body mass, making them significantly larger than those of many present-day animals.
