Which physiological changes are associated with aging?
What will be an ideal response?
Age-related physiological changes include: declines in muscle mass and bone density; weight loss and undernutrition; reduced functioning of the immune system. Declines in vision, hearing, taste, and smell often reduce appetite, food intake, and eating enjoyment. Older adults may also experience reduced saliva production, dysphagia, reduced gastric secretions, and slower GI motility. Brain function may slow because of an age-related decline in the levels of neurotransmitters and in blood flow.
