changes in body system

Question 1

GI system effects

Answer 1

• decrease tooth enamel
• decrease saliva = decrease bolus = breakdown carbs = decrease cleaning = decrease immunity
• decrease mucosa = decrease protection = decrease secretion = decrease nutrient breakdown and increase difficulty swallowing/decrease absorption
• decrease smooth muscle = decrease motility = dysphagia/ increase reflux and constipation/incontinence

Question 2

Cardiovascular effects

Answer 2

-Increase myocardial ischemia = decrease myocytes (muscle cells) and increase fibrosis
-Increase degeneration of valves
-Causes left ventricular hypertrophy (increase in size)
= decrease cardiac capacity = decrease ability to increase C.O as necessary and Decrease maximae HR
= exercise intolerance

Question 3

Blood vessels

Answer 3

• Decrease muscle mass and increase fibrosis = decrease compliance of blood vessels (increase stiffness)
• Endothelial dysfunction and degeneration + inflammation = decrease gas exchange
• Increase atherosclerosis
  -Decrease compliance of blood vessels = Increase BP (systolic)
  -Decrease ability to respond to blood pressure changes (homeostatic response) = orthostatic hypotension
