- One healthy kidney is enough to live normally.
- Filtered/day — ~180 L

- Who is the The Kidneys poster for?
- The Kidneys 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 Kidneys poster?
- They filter your entire blood volume roughly every half hour, all day. A wall chart earns its place by being glanceable from where the work is happening, so The Kidneys belongs on the wall where that health work actually happens, within glancing distance, rather than filed away.
- What other posters go with The Kidneys?
- Blood, Blood Types and The Body Systems sit alongside The Kidneys 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 Kidneys poster free to download and print?
- Yes. The Kidneys 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 Kidneys poster print at?
- The Kidneys 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 Kidneys loses nothing.Printing guide
