Erythropoietin (EPO) and RBC Production Feedback Loop Bell Ringer

Description

This is a no-prep bell ringer, warm-up, or exit ticket on one narrow concept in A&P II: the negative feedback loop that regulates erythropoietin release and red blood cell production. Print it or project it, and it runs in five to ten minutes with no setup beyond the two pages provided. Inside is a one-to-two-page reference sheet covering the feedback loop’s key values and rules, written in a students-think-this-but-actually format that names the specific misconception before correcting it, so it doubles as a quick reteach page. Paired with it is a 10-question self-check with a full answer key. Every option, correct and incorrect, has a written explanation, and every question was independently verified before publication; the ones that failed verification were removed rather than reworded, so what remains is confirmed accurate rather than smoothed over. Because each wrong answer explains the misconception behind it, the self-check works as a real diagnostic rather than a raw score. If a class misses question 6 and most picked the same wrong option, the answer key tells you which false belief about oxygen sensing or hormone release to reteach, not just that six questions were wrong. This fits an A&P II or physiology classroom that needs a fast check on EPO and RBC feedback specifically, as a warm-up before a related lecture, an exit ticket after one, or a sub-day handout that needs no explanation to run. It is built around this one concept only. It is not a unit review, not a full endocrine or hematology study guide, and not a multi-day packet, so pair it with your own materials if you need broader coverage.
