Introduction: In this lab, you will be examining many characteristics of a rat’s anatomy. Dissections help researchers get a 3-dimensional picture of how the systems of a body work together. Now you’ll have the opportunity to see how the respiratory, digestive and circulatory system are arranged spatially. The Classification of the Rat (Rattus norvegicus): Kingdom: Animalia Phylum: Chordata Subphylum: Vertebrata Class: Mammalia Order: Rodentia Family: Muridae Genus: Rattus Species: Norvegicus Note: Dissection does not mean cut up.” Rather, it means expose for viewing.” Therefore, please “to “to follow the instructions outlined in this lab for proper dissection technique and never cut more than is absolutely necessary to expose an organ.
