immune system failure theory
System loses ability to protect the body from disease and becomes more susceptible to diseases that eventually kill us; older people become more susceptible to disease such as pneumonia.
disengagement theory
ex: if an older adult who has heart disease may develop shortness of breath may be unable to continue daily walks with their friends. The older adult will develop less contact with their friends which may lead to fading friendships.

longevity
aged 80 years old
age associated memory
-normal physical changes of aging
-begin occurring early in adulthood
-often goes unnoticed until a problem develops
cardiovascular
-increased heart size, decreased cardiac output, less elastic blood vessels.
Respiratory
-thickened alveolar walls, weakened respiratory muscles, decreased vital capacity.
-respiratory failure, sob, lack of o2 to meet body needs.
musculoskeletal
-thinned intervertebral disks, decreased bone calcium, smaller muscle mass, less elastic ligaments and tendons
-osteoarthritis, osteoporosis, tendonitis, and rheumatoid arthritis.
integumentary
-thinner, drier skin; loss of subcutaneous fat, slower rate of hair and nail growth
-pressure injuries, resulting from friction or shears
urologic
-decreased bladder capacity and tone
-loss of nephrons, decreased sphincter control
-urinary incontinence
neurologic
-presbyopia (farsightedness)
-cataracts; decreased peripheral vision
-presbycusis (age related hearing loss)
-decrease in touch, smell, and taste receptors; slowed reaction time; balance may be affected
-decreased sensory perceptions; safety risk, fall risk, and decreased appetite
endocrine
-Slowed production of all hormones, decreased metabolic rate.
-delayed insulin response, hyperthyroidism, or hypothyroidism
gastrointestinal
-decreased secretion of saliva and other digestive enzymes, slowed peristalsis, slowed liver and pancreatic functions, reduced absorption of nutrients
-constipation, malnutrition, and anemia
