A structural change in the tissue caused by injury or disease is known as what?

A structural change in the tissue caused by injury or disease is referred to as a lesion. Lesions can manifest in various forms, such as cuts, sores, or any abnormality affecting the normal structure of tissue. They often indicate a disruption or alteration due to factors like infection, inflammation, or physical damage.

In the context of this question, while terms like injury, scar, and wound are related to physical damage or changes to tissue, they don't specifically encompass the broad concept of a structural change that can arise from various underlying conditions or diseases. An injury typically refers to the act of sustaining harm, while a wound usually signifies an external break in the skin or tissue. A scar is more of a permanent result of healing following an injury but doesn't describe the underlying alterations in tissue structure that a lesion would. Therefore, the term lesion most accurately describes the structural changes to tissue caused by injury or disease, making it the correct answer.
