What is an infarct?

• A. Excessive bleeding
• B. Dead tissue due to lack of blood supply
• C. Splitting of skin
• D. Low oxygen levels

Answer: (B)

An infarct refers specifically to an area of dead or damaged tissue resulting from an interruption in blood supply. When blood flow to a specific part of the body is restricted or blocked, oxygen and nutrients can no longer reach those tissues, leading to cell death and ultimately, an infarct. Common examples are myocardial infarction (heart attack) or cerebral infarction (stroke), where tissue damage occurs in the heart or brain, respectively, due to lack of blood flow. The other choices do not accurately describe an infarct. Excessive bleeding pertains to hemorrhage, which involves a significant loss of blood but does not necessarily mean that the tissues are dead due to lack of blood supply. Splitting of skin pertains to mechanical injuries rather than cellular death from oxygen deprivation. Low oxygen levels can contribute to tissue damage but do not directly define an infarct, as it is the lack of blood supply that creates the condition of dead tissue.
