Collection of blood is subcutaneous tissue is called :
Answer: A
A collection of blood in the subcutaneous tissue is a bruise (contusion).
Blunt force ruptures small blood vessels under intact skin, and blood escapes into the subcutaneous tissues. The colour changes over the following days (red, blue, green, yellow) as haemoglobin breaks down, which helps estimate the age of an injury.
Stab, lacerated and chop wounds all break the skin. A stab wound is made by a pointed weapon and is deeper than it is long; a laceration is a tear of skin by blunt force; a chop wound is made by a heavy sharp-edged weapon such as an axe. None is a collection of blood under unbroken skin.
