Sample item

What cell lineage gives rise to platelets?

Original practice item, not a recalled exam question. Nothing here is recorded.

The answer and the reasoning

B. Megakaryocyte

The core Blood physiology relationship supports Megakaryocyte; it is the response that directly accounts for the structural location or physiological change described.

Option by option

  • A. Lymphocyte

    Lymphocyte does not fulfill the structural or functional role requested.

  • B. Megakaryocyte (correct)

    Correct. Megakaryocyte is directly supported by the central clue.

  • C. Neutrophil

    Neutrophil is associated with a different blood physiology relationship.

  • D. Erythrocyte

    Erythrocyte is not consistent with the key finding in the stem.

How should I study Blood physiology?

For each system, sketch the key graph (pressure–volume loop, oxygen dissociation curve, nephron handling) and explain it aloud. Then use the flashcards and the other Physiology questions on this site to test what stuck.

Is this a real NEET PG question?

No. It is an original practice item (editorial status: sample, version 1). NextPrep does not publish recalled or leaked questions, and independent faculty review of this item has not been completed yet, so confirm important facts in a standard textbook.
