In science we have been learning about human body systems. We just had a test on interconnectedness of human body systems. We made bubbles for each system and had to draw arrows to different systems to another of things that transfer through the system. Sometimes if you didn’t know where the part of the system came from you can draw a cloud. After drawing this stock and flow/bubble map I noticed how all the systems are so connected, and the circulatory connects to most of the systems.
