Rats are chosen for dissection due to their physiological similarities to humans. Like humans, rats possess a four-chambered heart, a diaphragm for respiration, and a highly developed nervous system. While certain specialized structures exist—such as the cecum for cellulose digestion and the lack of a gallbladder in most strains—the fundamental blueprint remains remarkably consistent across mammalian species. This makes the rat an invaluable tool for studying how specialized tissues aggregate to form organs, and how those organs work in concert to maintain homeostasis. Safety and Ethical Considerations

The Norway rat ( Rattus norvegicus ) has been a model organism in biomedical research for over 150 years due to its short gestation period, docile nature, and, most importantly, its possession of a mammalian body plan that is homologous to that of Homo sapiens . While modern imaging techniques such as MRI and CT scanning offer non-invasive alternatives, direct dissection remains the gold standard for learning three-dimensional spatial relationships among organ systems. This laboratory exercise employs guided dissection of a preserved, double-injected (latex-colored arteries red, veins blue) rat to examine the macroscopic anatomy of the digestive, respiratory, circulatory, and urogenital systems.
