Who is the Blood poster for?

Blood 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 Blood poster?

More than half of blood is water with proteins dissolved in it. The cells are the minority. A wall chart earns its place by being glanceable from where the work is happening, so Blood belongs on the wall where that health work actually happens, within glancing distance, rather than filed away.

What other posters go with Blood?

Blood Types, The Body Systems and The Cell sit alongside Blood 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.Blood TypesThe Body SystemsThe Cell

What size does the Blood poster print at?

Blood 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 Blood loses nothing.Printing guide
