Hi again! Sorry we didn’t I didn’t get to answer all the questions properly. Time just flies on those chats! Wish they were longer :). Blue whale’s are the biggest of all animals. Their heart weighs 600 kilograms (1,300 lb) and is the largest known in any animal.( if you’re that big you’re gonna need a big pump!). That’s about the size of a VW bug/Mini cooper. A blue whale’s aorta (major blood vessel) is about 23 centimetres (9.1 in) in diameter & they have 14,000 pounds (6,400 kg) of blood circulating in in their body (wow!). You can see a to-scale model of a blue whale’s heart here: http://www.buzzfeed.com/daves4/the-size-of-a-blue-whales-heart-cg3 Hope that answers your question Jade. Have a good one 🙂
