BCG Aging Process & Physiology — Questions and Answers
Question 1: What is a common cardiovascular change associated with normal aging?
- Decreased heart size
- Increased elasticity of arteries
- Thickening of arterial walls (Correct answer)
- Enhanced cardiac output
Correct answer: Thickening of arterial walls
Arterial walls tend to thicken and lose elasticity as part of the aging process, leading to increased systolic blood pressure.
Question 2: Which cognitive change is considered a normal part of aging?
- Severe memory loss
- Slowed processing speed (Correct answer)
- Delirium
- Disorientation to place
Correct answer: Slowed processing speed
Slower information processing and recall are common and normal cognitive changes seen in healthy older adults.
Question 3: How does aging typically affect bone health?
- Increased bone regeneration
- Stable bone mass
- Enhanced bone flexibility
- Decreased bone density (Correct answer)
Correct answer: Decreased bone density
Aging is associated with a gradual decrease in bone density, which increases the risk of fractures, especially in women post-menopause.
Question 4: What sensory change is commonly experienced by older adults?
- Improved night vision
- Presbyopia (Correct answer)
- Increased visual acuity
- Enhanced peripheral vision
Correct answer: Presbyopia
Presbyopia, the loss of near vision, is a common age-related change caused by the lens of the eye becoming less flexible.
Question 5: What change in the respiratory system occurs with aging?
- Increased alveolar surface area
- Enhanced gas exchange
- Decreased lung elasticity (Correct answer)
- Improved diaphragmatic function
Correct answer: Decreased lung elasticity
Aging reduces lung elasticity and chest wall compliance, leading to decreased vital capacity and reduced oxygen exchange.
Question 6: Which of the following is a normal gastrointestinal change in the aging process?
- Faster digestion
- Increased peristalsis
- Decreased GI motility (Correct answer)
- Improved nutrient absorption
Correct answer: Decreased GI motility
Slower gastrointestinal motility is common in older adults and can contribute to constipation if not managed properly.
