I need to do a project for my anatomy class. I need to make a human heart showing blood flow. Can you recommend some site to help me. I don't want to spend a lot of money of the items needed. Please help
Please only post your questions once. Repeating posts will not get a quicker response. In addition, it wastes our time looking over reposts that have already been answered in another post. Thank you.
