This set of 7 individual, museum-quality hearts is perfect for comparative anatomy studies. Each 2-part model is life size or slightly enlarged to allow easy identification of detailed external and internal structures. Compare and contrast the structure and function of the 2-, 3-, and 4-chambered heart while studying topics such as the circulatory system and evolution. Blood flow direction is also marked on each model, making it easy to discuss advantages and disadvantages of each variation.
A heart model from each of the following species is included: fish (Esox lucius), frog (Rana esculenta), tortoise (Emys orbicularis), crocodile (Crocodylus niloticus), bird (Aquila chrysaetos), dog (Canis lupus familiaris), and human (Homo sapiens). Significant structures are numbered and a key is included. Each model is on a stand with green base.
