What decreases/increases occur in the cardiovascular system in the older adult?
Decreased cardiac output
Decreased elasticity and stiffening of arteries and veins.
Decreased response to changes in heart rate and blood pressure.
Decreased number of cells in sinoatrial and atrioventricular nodes, bundle of His, and right an left bundle branches leads to slowed conduction and dysrhythmias.

Decreased subcutaneous fat, oil secretions, sensory receptors.
Less elastic, skin cells thinner, less collagen.
Lentigo senilis: irregular areas of dark pigmentation on back of hands, on arms and face.
Sweat and sebaceous glands less active.
Fragile and more easily injured tissue.
What reproductive changes occur in older adults?
Narrowing, stiffness, and dryness of vagina.
Decreased sperm production.
What changes in the senses occur in older adults?
Presbyopia: age-related farsightedness, which is a lack of ability for eyes to accommodate to close objects.
Dry and irritated cornea, decrease in tears.
Presbycusis: decreased hearing, particularly of high-pitched sounds.
Decreased smell and taste.
What changes occur in the kidneys of older adults?
Decreased glomerular filtration rate
Decreased flow to kidneys
Decreased bladder tone and capacity
Incontinence related to bladder capacity
What cognitive changes occur with older adults?
Reduced ability to block out irrelevant information.
Decrease in long-term memory
Difficulty with abstraction and mental flexibility.
Difficulty maintaining sustained attention to a task or event.
Some react with minor anxiety or distress and others develop maladaptive coping mechanisms.
Ability to adapt to changes throughout the lifespan ensures a better reaction to the changes inherent in the aging process.
