PN 2005 FINAL EXAM SOLVED 100%
CORRECT STUDY GUIDE QUESTIONS AND
SOLUTIONS 2026 CORRECT ANSWERS
GRADED A+
⩥ changes to the cells of the body. Answer: -number of cells gradually
reduced
-leaving fewer functional cells in the body
-lean body mass reduced
-fat tissue increase s until the sixth decade of life
-total body fat as a porpotion of the body composition increases.
-Cellular solids and bone mass are decreased
-Extracellular fluid remains failry constant
-where as intracellular fluid is decreased
-resulting in less total body fluid
-This decrease makes dehydration a significant risk to older adults
⩥ Gastroinstestinal System age changes. Answer: -decreased taste
sensation
-esophagus more dilated
-reduced saliva and salivary ptyalin
-liver smaller in size
,-reduced instestinal blood flow
-decreased esophageal motility
-atrophy of gastric mucosa
-decreased stomach motility, hunger contractions, and emptying time
-less production of hydrochloric acid, pepsin, lipase, and pancreatic
enzymes
- fewer cells on absorbing surface of intestines
-slower peristalisis
-tongue atrophies
-there is thinning of oral mucosa and a weakening of the muscles
involved in mastication
reduced elasticity of stomach
stomach has a higher ph
⩥ Urinary System aging. Answer: -decreased size of renal mass
-decreased tubuler function
-decreased bladder capacity
-decrease in nephrons
-betweenages 20 and 90, renal blood flow decreases 53% and glomerular
filtration rate decreases 50
-weaker bladder muscles
-nocturia
-weak bladder muscles
,⩥ ageing of the female reproductive system. Answer: -fallopian tubes
atrophy and shorten
-ovaries become thicker and smaller
-cervix becomes smaller
-drier less elastic vaginal canal
-flattening of labia
-endocervical epithelium atrophies
-uterus becomes smaller in size
-endometrium atrophies
-more alkaline vaginal environment
-loss of vulvar subcutaneous fat and hair
-vulva atrophy
-vaginal epithelium becomes thin
-cervix, uterus, fallopian tubes, ovaries atrophy
-uterus and overies decrease in size
- breasts sag and less firm
-some retraction of nipples
-fibrosis and calcification of the terminal ducts
⩥ Aging of the male reproductive system. Answer: -fluid-retaining
capacity of seminal vesicles reduces
, -possible reduction in sperm count
-venous and arterial sclerosis of penis
-prostate enlarges in most men
-seminal vesicles having a thinner epithelium
-replacement of muscle with connective tissue
-structural changes in the seminiferous tubules include fibrosis, thinning
of epithelium,thickening of the basement membrane
-narrowing of the lumen
-atrophy of the testes
-reduction is testicular mass
-more time required for an erection
⩥ aging musculoskeletal system. Answer: -muscle mass, muscle
strength, muscle movements decreased
-age related loss of muscle mass, strength and function= sarcopenia
- tendons shrink and harden
-reflexes are lessened in the arms and nearly lost in abdomen
-shortening of vertebrae
-between 20 and 70 height decreases approx 2 inches
-bones more brittle
-slight knee flexion
-decrease in bone mass and bone mineral
-slight kyphosis
