Advantages and disadvantages of things

Advantages of increased heart rate and breathing rate:

  • Arteries dilate so increased blood flow to the muscles, which means increased oxygen and glucose supply
  • Increases the rate of carbon dioxide removal - good for RESPIRATION
  • Glycogen gets broken down into glucose which the muscles use as energy for respiration
  • Heat removed from the body through sweat

Advantages of kidney dialysis:

  • Readily available
  • Can be done at home
  • No rejection can occur

Disadvantages of kidney dialysis:

  • Very restricting - sessions can take up to10 hours at a time
  • Has to be done regularly i.e every few days
  • Life revolves around it
  • Diet had to be regulated

Advantages of kidney transplant:

  • Less restricting-don't have to spend hours connected to a machine
  • Cheaper
  • Can lead a normal life afterwards i.e. don't have to regulate diet
  • High success rate

Disadvantages of a kidney transplant:

  • Rejection can occur
  • Have to take immunosupressant drugs which makes you more prone to disease
  • Bone marrow has to be irradicated
