Sample item

Which haemodynamic process makes inflamed tissue red and warm through active arteriolar dilation?

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

The answer and the reasoning

D. Hyperaemia

Hyperaemia is active arteriolar dilation that increases blood flow and produces red warm tissue, unlike passive congestion from impaired venous drainage.

Option by option

  • A. Intravascular thrombosis

    Clot formation is thrombosis.

  • B. Complete cessation of perfusion

    No perfusion is ischaemia.

  • C. Passive venous congestion

    Congestion is passive venous accumulation.

  • D. Hyperaemia (correct)

    Correct: active arterial inflow defines hyperaemia.
