Blood Crossword Puzzle

Define key blood-cell terms (erythrocyte, leukocyte, platelet, agranulocyte, granulocyte) from functional descriptions.

Identify the blood-typing terms universal donor and universal recipient and describe the reaction that follows a mismatched transfusion.

Explain hemostasis and the role platelets and clotting play in stopping blood loss.

Use as a post-unit review once cell types, blood typing, and clotting have already been taught, since the clues assume prior vocabulary instruction rather than teaching the terms directly.

Have students complete the puzzle independently, then use the included answer key for fast self-checking or grading.

Pair with a labeled diagram of blood components for students who benefit from a visual alongside the definitional clues.

Vocabulary recall from definition — students work backward from a functional description (e.g. "the process of blood cell formation") to the matching term (hematopoiesis).

Blood-cell classification — clues distinguish red cells, white cells, and platelets, and further separate white cells into granulocytes and agranulocytes.

Blood-typing reasoning — clues require distinguishing the universal donor from the universal recipient and naming the transfusion-mismatch reaction.
