Stuffed Animals. Thereâs TONS of stuffed Disney animals and friends on eBay. One of the most expensive is this Genie doll, which is listed for $1,000. I know I have some of these somewhere, but mine are definitely more, ah, âwell-lovedâ than this one.

The heart pushes blood through the tissues and provides a constant force for blood flow to occur. The heart provides enough force to propel the blood through the arteries and veins in the body.
