Which condition represents tissue death from degradation?

The condition that represents tissue death from degradation is necrosis. This process involves the unregulated death of cells in response to injury or disease, leading to the breakdown of cellular components. Necrosis often results from factors such as lack of blood supply, infection, or exposure to toxins. It is characterized by the degradation of cell structures and the release of cellular contents into the surrounding tissue, which can lead to inflammation.

While infarction, ischemia, and dehydration involve various forms of tissue injury, they do not specifically define the process of cell death due to degradation. Infarction is a specific type of necrosis that occurs when blood flow to a tissue is obstructed, causing tissue damage. Ischemia refers to a reduction in blood flow to a tissue, which can lead to necrosis if prolonged, but it does not itself indicate tissue death. Dehydration may cause cellular dysfunction but does not directly cause tissue death in the same way necrosis does. Therefore, necrosis is the most accurate representation of tissue death due to degradation.
