What condition is described by tissue death resulting from a lack of blood supply?

The condition characterized by tissue death due to a lack of blood supply is known as infarct. When blood flow to a specific area is severely reduced or cut off, tissues in that area become deprived of necessary oxygen and nutrients, leading to cell death. This can occur in various organs, notably in the heart (myocardial infarction) and the brain (cerebral infarction), and can result from conditions such as blockages in blood vessels or severe hemorrhage.

Keloid refers to an overgrowth of scar tissue that occurs at the site of an injury, rather than tissue death. Ischemia denotes a state of reduced blood flow to an organ or tissue, which can lead to infarction, but it is not synonymous with tissue death itself. Incontinence is unrelated to blood supply issues, referring instead to the inability to control bladder or bowel functions. Thus, the definition and implications of infarct align perfectly with the context of tissue death due to a lack of blood supply.
