how does a slower metabolic rate effect the cells - Answer✔✔-mitosis slows down, decreased
tissue repair
what is menopause - Answer✔✔-ovaries cease to produce estrogen and progesterone, which
raises follicle-stimulating hormone and luteinizing hormone (biofeedback mechanisms), and
ultimately the ovaries cease to respond to FSH and LH
what happens to vaginal ph as women age past menopause - Answer✔✔-alkaline, increased r/f
infection
what is BPH - Answer✔✔-benign prostatic hypertrophy, central part of the gland around the
uretthra hypertrophies, resulting in some degree of obstruction of the urethra. , surgery if
urinary flow impaired
why is cancer of the prostate, uterine, and breast, more likely in older age - Answer✔✔-altered
hormonal levels
why are elderly increased risk for bruising and skin injury - Answer✔✔-dermis is thinner and
subcutaneous tissue is diminished, fewer capillaries are present and cell proliferation is
decreased, the numbers of sensory receptors in the skin and mucosa decline
why are elderly people have dry and wrinkled skin - Answer✔✔-elastic fibers are reduced and
collagen fibers become less flexible
what interferes with cardiac muscle conduction and contraction - Answer✔✔-fatty tissue and
collagen fibers accumulate in the heart with aging
