The Immune Response, step by step

The specific immune response to a novel pathogen.

  1. PhagocytosisA macrophage engulfs the pathogen and presents its antigen.
  2. T helper activationA matching helper T cell binds and divides.
  3. Clonal selectionThe matching B cell is activated and proliferates.
  4. Plasma cellsSecrete large quantities of specific antibody.
  5. Memory cellsRemain, giving a faster and larger secondary response.

Primary vs secondary

  • Primary: slow, days, lower antibody peak
  • Secondary: rapid, higher, longer lasting
  • That difference is what vaccination exploits

Cytotoxic T cells destroy infected body cells directly, which antibodies cannot reach.

Questions about the The Immune Response poster

What’s on the The Immune Response poster?
5 numbered steps, with a full worked run-through. The specific immune response to a novel pathogen. Phagocytosis — A macrophage engulfs the pathogen and presents its antigen.; T helper activation — A matching helper T cell binds and divides.; Clonal selection — The matching B cell is activated and proliferates.; Plasma cells — Secrete large quantities of specific antibody.; Memory cells — Remain, giving a faster and larger secondary response.. Cytotoxic T cells destroy infected body cells directly, which antibodies cannot reach.
Who is the The Immune Response poster for?
The Immune Response belongs to the Biology section rather than to a school year, because life science is not something one grade owns. Anyone learning physiology can pin it up — a beginner, a student mid-course, or someone revising years later.
When should you use the The Immune Response poster?
B cells make antibodies. T cells kill and coordinate. Both leave memory cells behind. A wall chart earns its place by being glanceable from where the work is happening, so The Immune Response belongs on the wall where that life science work actually happens, within glancing distance, rather than filed away.
What other posters go with The Immune Response?
Blood Glucose Control, The Cardiac Cycle and The Circulatory System sit alongside The Immune Response in the Biology section. Printed together they make a wall rather than a single sheet, which is how a reference set actually gets used.Blood Glucose ControlThe Cardiac CycleThe Circulatory System
Is the The Immune Response poster free to download and print?
Yes. The Immune Response downloads as a free PDF with no account, no email and no watermark, like everything else in the Biology 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 Response poster print at?
The Immune Response 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 Response loses nothing.Printing guide
