-forced expiratory volume reduced
|\ |\ |\
-blunting of cough and laryngeal reflexes
|\ |\ |\ |\ |\

-
changes to the cells of the body - CORRECT ANSWERS ✔✔-
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\
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
|\ |\ |\ |\ |\ |\ |\ |\ |\

|\ |\ |\ |\ |\ |\
-some retraction of nipples
|\ |\ |\ |\
-fibrosis and calcification of the terminal ducts
|\ |\ |\ |\ |\ |\
