A knife or a broken glass slices through the layers of the skin causing heavy bleeding. Which type of bleeding injury is it? A. abrasion B. laceration C. puncture

B. laceration

Explanation:

Abrasion - a scrape.

The skin is not scraped if layers of the skin are sliced.

Puncture - a wound usually caused by something sharp and pointed. The opening of the skin is small and the wound does not bleed much. So it's not a puncture.

Laceration - a wound produced by the tearing of body tissue, as distinguished by a cut.

Since the knife cut through layers of the skin which includes the tissue underneath, the injury is a laceration.
