Sample item

What is the main vascular effect of histamine?

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

The answer and the reasoning

D. Vasodilation and increased permeability

Histamine rapidly increases vascular permeability and causes vasodilation, allowing plasma proteins and leukocytes to enter inflamed tissue.

Option by option

  • A. Red-cell production

    Erythropoiesis is marrow function.

  • B. Arterial thrombosis only

    Thrombosis is not its main direct action.

  • C. Fibroblast collagen synthesis

    Fibroblasts synthesize collagen later in repair.

  • D. Vasodilation and increased permeability (correct)

    Correct: histamine drives early vascular inflammation.
