Sample item

What protein forms the structural mesh of a blood clot?

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

The answer and the reasoning

D. Fibrin

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

Option by option

  • A. Hemoglobin

    Hemoglobin does not fulfill the structural or functional role requested.

  • B. Albumin

    Albumin is associated with a different blood physiology relationship.

  • C. Transferrin

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

  • D. Fibrin (correct)

    Correct. Fibrin is directly supported by the central clue.

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.
