the human body that are unstable move around the body, causing harm to living cells.
This can disrupt metabolism and cell processes, leading to disease.
How does the free radical theory work? - answer During normal cell molecule
formation, electrons are shared with each other, but from aging or damage to cell DNA
from over exposure to radiation and pollution, the molecule splits and does not pair with
an electron, causing a free radical to be formed and that can harm cells.
What types of diseases does the free radical theory propose when these cells travel in
the body with aging? - answer cancers, diabetes, arthritis, atherosclerosis
What can be taken to neutralize free radicals? - answer antioxidants- in the form of
food, vitamins. they help to donate electrons from stale atoms
What is the cross linkage theory? - answer when free radicals interact or connect with
cell molecules and connective tissue that causes tissues to be damaged and unable be
repaired. when it is damaged, this can lead to disease and function problems in older
adults
What is connective tissue? - answer matrix that provides support, binds tissues in the
body such as organs, muscles, bones and joints, adipose tissues, cartilage, blood and

predetermined number of cell divisions that will occur during our lifetime, and that each
one is a tick of a clock. these are genetically predetermined and as older adults, these
cell divisions are slowed down, so more cell loss is perceived

adenoids, lymph nodes, thymus, spleen, appendix, help the body maintain
immunological function, and when the body is aged, these organs cannot function or
filter out harmful disease
What is the activity theory? - answer the idea that activity is important in maintaining
emotional health, independence, and functionality of the older adult. Activity is needed
to keep from isolation from society, engagement, life satisfaction and connectedness
