This refers to a decrease in efficiency or capacity of an organ or tissue that occurs naturally with age or due to disease.
Imagine if you have been using your smartphone for several years. Over time, it starts slowing down and doesn't work as efficiently as it used to. Similarly, our organs can also experience decline over time due to aging or illness.
Senescence: The condition or process of deterioration with age.
Degenerative Disease: Diseases which affect tissues and organs leading to their progressive loss of function.
