What is normal aging

CARDIOVASCULAR CHANGES. Changes in blood vessel walls, heart valvesDecreased cardiac outputDecreased peripheral circulationIncreased systolic blood pressureIncreased pulmonary vascular tension. RESPIRATORY CHANGES. Decreased cough reflexDecreased cilia ( removal of airway irritants)Decreased vital capacity Fewer alveoliIncreased chest wall rigidity/airway resistance.

Presentation Transcript

    1. What is normal aging? Changes in the various systems Cardiac Respiratory Gastrointestinal Musculoskeletal Neurological Sensory Endocrine Genitourinary/Reproductive Integumentary

    2. CARDIOVASCULAR CHANGES Changes in blood vessel walls, heart valves Decreased cardiac output Decreased peripheral circulation Increased systolic blood pressure Increased pulmonary vascular tension

    3. RESPIRATORY CHANGES Decreased cough reflex Decreased cilia ( removal of airway irritants) Decreased vital capacity Fewer alveoli Increased chest wall rigidity/airway resistance

    4. GASTROINTESTINAL CHANGES Decrease in saliva, gastric secretions, and pancreatic enzymes Smooth muscle changes -decreased esophageal peristalsis -decreased small intestinal motility Periodontal disease

    5. MUSCULOSKELETAL Decreased muscle mass and strength Decalcification of bones Degenerative joint changes

    6. NEUROLOGICAL CHANGES Degeneration of nerve cells Decrease in neurotransmitters Decrease in rate of conduction of impulses

    7. SENSORY CHANGES EYE- accommodation to near/far; lens changes EARS-loss of acuity; tympanic membrane changes TASTE- often diminished with fewer taste buds SMELL-often diminished TOUCH- skin receptors

    8. ENDOCRINE CHANGES GENERAL-hormone production altered THYROID- decreased secretion THYMUS-involution of thymus gland CORTISOL- anti-inflammatory hormone PANCREAS- secretion of enzymes & hormones

    9. GENITOURINARY/REPRODUCTIVE URINARY- fewer nephrons -decreased bladder capacity Male- enlarged prostate Female- reduced sphincter tone REPRODUCTIVE Male- sperm count diminishes - smaller testes Female- degeneration of female organs - decreased estrogen production

    10. INTEGUMENTARY CHANGES Loss of skin elasticity Pigmentation changes Glandular atrophy Thinning hair Atrophy of epidermal arterioles
