,chanes to the respiratory system -PO2 reduced as much as 15% between ages 20-
with age 80
-loss of elasticity and increased rigidity
-decreased ciliary action
-forced expiratory volume reduced
-blunting of cough and laryngeal reflexes
-by age 90 approx 50% increase in residual
capacity
-alveoli fewer in nuber and larger in size
-thoracic muscles more rigid
-reduced basilar inflation
-lungs become smaller in size and weigh with age
-trachea stiffens due to calcification of its
cartilage
-nose experiences connective tissue changes
reduce support
-gag reflex weaker
-alveoli are less elasic, develop fibrosis tissue and
contain fewer functional capillaries
, -kyphosis
-
changes to the cells of the body -number of cells gradually reduced
-leaving fewer functional cells in the body
-lean body mass reduced
-fat tissue increase s until the sixth decade of life
-total body fat as a porpotion of the body
composition increases.
-Cellular solids and bone mass are decreased
-Extracellular fluid remains failry constant
-where as intracellular fluid is decreased
-resulting in less total body fluid
-This decrease makes dehydration a significant risk
to older adults
, Gastroinstestinal System age -decreased taste sensation
changes -esophagus more dilated
-reduced saliva and salivary ptyalin
-liver smaller in size
-reduced instestinal blood flow
-decreased esophageal motility
-atrophy of gastric mucosa
-decreased stomach motility, hunger contractions,
and emptying time
-less production of hydrochloric acid, pepsin,
lipase, and pancreatic enzymes
- fewer cells on absorbing surface of intestines
-slower peristalisis
-tongue atrophies
-there is thinning of oral mucosa and a weakening
of the muscles involved in mastication
reduced elasticity of stomach
stomach has a higher ph
