Study Notes

Integumentary System Changes

Skin loses elasticity and becomes dryer, resulting in increased sensitivity to temperature changes, especially cold.

Musculoskeletal System Changes

Bones experience brittleness and a gradual loss of height; movement is generally slower.

Circulatory System Changes

Aging can cause weakness and dizziness; blood pressure may fluctuate, increasing or decreasing with age.

Respiratory System Changes

The rib cage becomes more rigid; individuals may experience frequent dyspnea (shortness of breath) and difficulties in coughing up secretions.

Nervous System Changes

Blood flow to the brain decreases; progressive brain loss can lead to diminished senses, including smell, vision, and hearing.

Digestive System Changes

Muscle action slows down, resulting in challenges with digestion; loss of teeth and decreased saliva production are also common.

Urinary System Changes

Kidneys shrink in size; poor circulation to the kidneys leads to reduced fluid production.

Endocrine System Changes

Hormone production diminishes over time; metabolic rate decreases, which may result in less overall alertness.

Reproductive System Changes

In women, vaginal infections may occur alongside hormonal changes; levels of testosterone decline in men.

General Characteristics of Aging Changes

Most physical changes related to aging are gradual and take place over a long period.
The rate and degree of these changes can vary between individuals.

Influencing Factors

Previous lifestyle choices, nutritional quality, economic status, and social environment can significantly impact aging changes.

Adaptation to Changes

Recognizing changes as normal parts of aging enables individuals to learn to adapt and cope effectively.

Osteoporosis: Loss of calcium and minerals from bones leads to increased risk of fractures.
Arthritis: Inflammation of the joints affects mobility and comfort.
Thrombus: This condition refers to the formation of blood clots, potentially leading to serious health issues.
Emphysema: Affected alveoli lose elasticity, impairing respiratory function.
Cataracts: The lens of the eye becomes cloudy or opaque, affecting vision.
Glaucoma: Characterized by increased intraocular pressure, which can lead to vision loss if untreated.
