As you age, your brain and nervous system go through natural changes. Your brain and spinal cord lose nerve cells and weight (atrophy). Nerve cells may begin to pass messages more slowly than in the past. Waste products or other chemicals such as beta amyloid can collect in the brain tissue as nerve cells break down.

Which of the following is an age related change in the nervous system quizlet?

Which of the following is a NORMAL age-related change of the nervous system? There is a decline in brain weight and a reduction in blood flow to the brain.

What are the normal effects of aging on the nervous system quizlet?

After age 30: Neurons decrease in number, neuroglial cells increase in size and number, axon thinning and decrease in number, dendrites decrease in number. Longer retrieval time for short term memory, categorization, and episodic memory.

Which of the following is an example of an age related change?

Abstract. Physiological changes occur with aging in all organ systems. The cardiac output decreases, blood pressure increases and arteriosclerosis develops. The lungs show impaired gas exchange, a decrease in vital capacity and slower expiratory flow rates.

Which of the normal age related changes in the respiratory system can increase the risk of infection in the older adult population?

Many factors, such as malnutrition and the presence of structural lung disease, increase the risk of respiratory infection in older individuals. Aging is also accompanied by a gradual decline in many aspects of immune function, and waning immunity is thought to be an important risk factor for pneumonia in the elderly.

What body systems are affected by aging?

Aging changes in organs, tissues, and cells
Striated muscles, such as those that move the skeleton (also called voluntary muscle)Smooth muscles (also called involuntary muscle), such as the muscles contained in the stomach and other internal organs.

How does aging affect the integumentary system quizlet?

Begin to decrease in number, stiffen, break apart, and disorganize into a shapeless, matted tangled. Lose some of their elasticity, thicken into clumps, and fray, an effect that is greatly accelerated in the skin of smokers.

How does aging affect the integumentary system?

Your skin is thinner, more fragile, and you lose some of the protective fat layer. You also may be less able to sense touch, pressure, vibration, heat, and cold. Rubbing or pulling on the skin can cause skin tears. Fragile blood vessels can break easily.

Which is an age-related change associated with the respiratory system?

Which is an age-related change in the respiratory system? Age-related changes associated with the respiratory system include decreased gas exchange and diffusing capacity. Age-related changes associated with the cardiovascular system include increased blood pressure and decreased cardiac output.

Which of the following is a normal age-related change of the respiratory system?

The changes in the respiratory system caused by aging generally include structural changes in the thoracic cage and lung parenchyma, abnormal findings on pulmonary function tests, ventilation and gas exchange abnormality, reduced respiratory muscle strength, and decreased exercise capacity.

Which of the following is an age-related change in the lungs quizlet?

Explanation: Age-related changes associated with the lung include increased thickness of the alveolar membranes, decreased elasticity of alveolar air sacs, increased diameter of alveoli ducts, and increased collagen of alveolar membranes.

What are age related changes?

With age, bones tend to shrink in size and density, weakening them and making them more susceptible to fracture. You might even become a bit shorter. Muscles generally lose strength, endurance and flexibility — factors that can affect your coordination, stability and balance.

Which change does not occur with age quizlet?

Which change does NOT occur with age? decreased compliance of the aorta.

What are the effect of aging?

Common health conditions associated with ageing

Common conditions in older age include hearing loss, cataracts and refractive errors, back and neck pain and osteoarthritis, chronic obstructive pulmonary disease, diabetes, depression and dementia.
