I’ve been trying to figure out how to go about locating a book from childhood. It was in the vein of Richard Scarry as far as similar illustrative style though it wasn’t focused on learning individual words. (The age range was basic reading level, thinking somewhere between 5-9?) There were descriptive informative blurbs/individual paragraphs and corresponding artwork. The one illustration I remember in detail pertained to what happens when you cut your finger (or maybe just get a cut anywhere). The red vs white blood cells fighting it out, etc. I vaguely recall it being oversized with a sky blue base color and variously illustrated on the covers. The overall theme seemed to be life/the world/perhaps how things work? I was reading this somewhere between 1986-1990. I fear this is likely not enough information though I appreciate the effort to help solve this book hunt.
