Jorin is building a model that shows how two different human body systems interact. He cuts a hole in a plastic tube, places a water filter in the hole, and connects a smaller tube directly to the filter. Jorin tests the model by running dirty water through the larger tube. Soon, the smaller tube begins to fill with clear water. Which two body systems is Jorin most likely using his model to simulate?
circulatory and urinary system

Blood consists of different types of cells — red blood cells, platelets, and white blood cells. Red blood cells transport oxygen throughout the body, platelets aid in blood clotting, and white blood cells help destroy and remove old cells and foreign substances. This is an example of how A. every part of the body contains different cells with unique and unrelated functions. B. only similar cells are grouped together so they can perform a singular function. C. different cells are unable to be grouped together within the same organ or organ system. D. the cells of the body are of different kinds and are grouped in ways that enhance how they function together.
