I need urgent help right now. I have a project and I have to make a 3D model of the pygmy hippo including: outside (skin, etc), respiratory system, digestive system, circulatory system, nervous system, excretory system, and endocrine system. I can't find a picture of any of these systems anywhere on the web but they have to be somewhere I'm guessing and I'm very bad at researching so please please help! Thank you so much
