Abstract: Network science and graph theory applications have spread widely to help in understanding how human body features are linked to graph network structure, thus providing a conceptual framework that can help in reducing the analytical circulatory complexity and underlining how network topology can be used to characterize circulatory diseases [1]. The central goal of this study was to verify the possibility of creating a structural network representing the human blood circulatory system and to describe the relationship between the human bodies in graph theory basics. Graph theory concepts were applied to 6 organs which contain selected 162 body parts and 217 links, representing the blood circulatory system.
