Exam 1 - CN (normal aging) Flashcards
age-related changes in body composition
- decreased body mass
- decreased elasticity and flexibility of muscles
- decreased total body water
- increased fat tissue
sarcopenia
decrease in muscle, increase in fat
considerations for changes in body composition
- effects of medications
- changes in diet
- decrease sodium intake
- reduce calorie intake
- increase intake of protein, calcium, and vit D
age-related decrease in kidney function affects
medications metabolized by the body
age-related changes in the cardiovascular system
- heart muscles thicken
- valves enlarge and stiffen
- muscular contraction force decreases
tachy
too fast
myo
muscle
infarct
dead tissue
considerations for changes in the cardiovascular system
- elderly person uses O2 less efficiently
- lowered ability to maintain physical activity for long periods of time
- safer w/ low intensity exercise
age-related changes in gastrointestinal system
- decreased contraction of esophageal muscles
- diminished secretion of digestive juices
- diminished efficiency of small intestine
- decreased contraction of colon
- decreased mass of liver, gallbladder, and pancreas
The gi system decreased in
size, mass, & efficiency
considerations for changes in the GI system
- diet changes - may need to reduce fat and sugar intake
- remain upright during and after meals to aid digestion
- avoid eating late in the evening
age-related changes in the endocrine system
- F experience decreased production of hormones (estrogen & progesterone)
- M & F experience decreased productions of hormones (testosterone, thyroid hormones, growth hormones, insulin)
considerations for changes in the endocrine system
- hormone replacement therapy
age-related changes in respiratory system
- decreased max capacity
- decreased lung elasticity
- vital capacity declines
- cilia reduced
- decreased cough
respiratory physician
pulmonologist
considerations for changes in the respiratory system
- remain active
- pace tasks
- avoid strenuous activities
age-related changes in the CNS
- neuron and glial cell loss
- decreased brain weight by 10%
- accumulation of lipofuscin (fat)
- slower neuronal transmission
- increased reaction times (takes longer to react)
considerations for changes in the CNS
- decrease factors which compound neuronal loss (smoking, alcohol, diet, lifestyle)
- allow more time for responses
- allow more time for decisions
- compensate for extra time requirements
