IMMUNE SYSTEM SIMULATOR Here it is, the Immune System Simulator! Use https://preview.scratch.mit.edu/#219549911 for less/no lag. Click on Try It!, then click on the full-screen button, and then on the green flag. Click the green flag to start this simulation! INSTRUCTIONS You can use the numbers and 'Q' to summon more of each type of white blood cell or pathogen. Which white blood cells are which and what they do is in the Notes and Credits description below. :) Please leave a love if you enjoyed!
UPDATES: Regulatory T-cell Functions: 1. press d and a at the same time to shut down all white blood cells 2. press s to shut down all white blood cells touching the mouse Neutrophils do not restart at the bottom of the screen when you press 0 anymore. There is less lag now. Everything by @CodeBit. INFORMATION ON THE SIMULATION & KEY/LEGEND The huge pale purple cell is a macrophage, an upgraded version of the monocyte. It can eat about 75-100 pathogens before it dies. The purple cells with three lobes in them coming up from the bottom are the neutrophils, which are being generated in the bone and are going to the site of infection. They die after having ingested just a few pathogens, forming a gooey substance called pus. It's eaten by macrophages. The green cells with the little Y's on them are B-cells, or more specifically, plasma cells. They mass produce Y-shaped antibodies that only bind to certain pathogens with the matching antigens. The plasma cells each only make one type of antigen, but there are four types, represented by the letter on their head that appears sometimes. The plasma cells are triggered to make antibodies when they are bumped into by another type of cell - the T-cells. These are the blue cells. Most of them call for other white blood cells to come join the fight, some are cytotoxic t lymphocytes that kill off infected body cells, and some target the pathogens that have been flagged by the antibodies. The T-cells in this simulator attack the pathogens that have been flagged. The yellow cells floating around and are stunned by the orange antibodies are a type of pathogen. It's gobbled up and fought by everything, and is relatively weak. The dark green cells moving around and stunned by the round green antibodies are a non-specific type of germ. They are easily killed because they are stunned for a very long time. The pink 'cells' moving around that are stunned by the large round pink antibodies are viruses. They are damaged less by neutrophils and a bit more resistant to T-cells. Lastly, there are some dark green ovals floating around. These are bacteria. They are not stunned for very long but are pretty weak. Watch the immune system battle!
