Which term describes wasting away or deterioration?

• A. Atrophy
• B. Alzheimer's Disease
• C. Angina
• D. Pulse Oximetry

Answer: (A)

Wasting away or deterioration describes atrophy. It refers to the shrinkage in size or function of tissue or an organ, often due to disuse, aging, or disease. For example, when muscles aren’t used, they can become smaller, and brain tissue can show reductions in some conditions. The other terms describe different things: Alzheimer’s disease is a specific progressive brain disorder that leads to dementia, not the general process of wasting away; angina is chest pain from the heart not receiving enough blood flow; pulse oximetry is a method for measuring how saturated the blood is with oxygen, not a description of tissue decline.
