Fever, swelling and fatigue are the immune response, not the infection. They are the cost of the defence.
Who is the The Immune System poster for?
The Immune System belongs to the Body & health section rather than to a school year, because health is not something one grade owns. Anyone learning anatomy can pin it up — a beginner, a student mid-course, or someone revising years later.
When should you use the The Immune System poster?
One responds in minutes to anything. The other takes days but never forgets. A wall chart earns its place by being glanceable from where the work is happening, so The Immune System belongs on the wall where that health work actually happens, within glancing distance, rather than filed away.
What other posters go with The Immune System?
Blood, Blood Types and The Body Systems sit alongside The Immune System in the Body & health section. Printed together they make a wall rather than a single sheet, which is how a reference set actually gets used.BloodBlood TypesThe Body Systems
Is the The Immune System poster free to download and print?
Yes. The Immune System downloads as a free PDF with no account, no email and no watermark, like everything else in the Body & health section. Print as many copies as you like for a home, a classroom, a library or a tutoring group; reselling the file is the only thing the licence rules out.Read the licence
What size does the The Immune System poster print at?
The Immune System is a vector PDF laid out for US Letter, and prints on A4 with Fit to page — the same file, no separate download. Because every mark on it is drawn rather than photographed, it stays sharp enlarged to A3, A2 or A1 at a copy shop. Colour carries emphasis only, so a greyscale print of The Immune System loses nothing.Printing guide
