Study Notes
Reduced Elastin and Increased Collagen Cross-Links
- Reduced elastin combined with increased collagen cross-links results in decreased elasticity and stiffness of tissues.
Irreversible Changes in Organ Function
- Irreversible changes in the function of most organs can be shown to occur after the age of 70.
Hair Turning Gray
- Hair turning gray with age is caused by a decrease in melanin production by melanocytes in the hair follicles.
Physiological Processes Affected by Normal Aging
- Normal aging affects all physiological processes, leading to a decline in homeostasis and functional reserve.
Musculoskeletal and Neuromuscular Changes with Aging
- Decreased muscle mass and strength
- Reduced bone density and increased risk of osteoporosis
- Decreased range of motion and joint flexibility
- Slower nerve conduction velocity and decreased reaction time
Medical Term for Residual Lung Volume
- The medical term for the volume of air remaining in the lungs after a maximal expiratory effort is Residual Volume.
Term for Air Breathed During Normal Respiration
- The term referring to the amount of air breathed in or out during normal respiration is Tidal Volume.
Forced Expiratory Volume (FEV) Measurement
- Forced expiratory volume (FEV) measures the volume of air expelled from the lungs during a forced exhalation in a given time period.
Sum of Inspiratory Reserve, Tidal, and Expiratory Reserve Volumes
- The sum of Inspiratory Reserve volume, Tidal volume, and Expiratory Reserve volume is known as Inspiratory Capacity.
VO2 Max Measurement
- VO2 max measures the maximum rate of oxygen consumption during exercise.
