Sample item

What is the main function of platelets?

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

The answer and the reasoning

B. Primary hemostasis

The relevant Blood physiology principle makes Primary hemostasis the best answer because it directly explains the structure or physiological response in the stem.

Option by option

  • A. Antibody production

    Antibody production is associated with a different anatomical or physiological role.

  • B. Primary hemostasis (correct)

    Correct. Primary hemostasis directly follows from the core blood physiology relationship.

  • C. Oxygen transport

    Oxygen transport does not correspond to the structure or response being tested.

  • D. Glucose storage

    Glucose storage is not supported by the key clue provided in this item.

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?
