Which of the following is a common effect of necrosis?

Necrosis refers to the process of uncontrolled cell death in tissues due to factors like injury, infection, or lack of blood supply. A common effect of necrosis is the loss of function in the affected area, which occurs because the cells that die can no longer perform their normal biological activities. As tissues become necrotic, the overall structure and functionality of the area deteriorate, leading to various complications depending on the location and severity of the necrosis.

In contrast, regeneration of tissue, formation of new blood vessels, and increased sensitivity in the skin are processes associated with healing or repair rather than necrosis itself. While tissues may eventually heal after necrosis occurs, the immediate effect of necrosis is the impairment of function in the affected region. Thus, emphasizing the nature of necrosis provides clarity on how tissue and organ function is compromised during this pathological process.
