biology

• liver roles

  remove excess protein

  deamination

  break down lactic acid
• liver roles

  remove excess protein deamination

  break down lactic acid

  convert unused glucose to glycogen and stores
• how glucose moved

  absorbed by diffusion into bloodstream

  blood delivers to muscle in capillaires
• breathing rate = vol of breath increases , bring in more oxygen less carbon dioxide
• heart rate increase

  supply muscles extra oxygen and glucose removes co2
• lactic acid build up = cramps

  glycogen low in muscles, more glucose used - tired, fatigued
• blood flow to muscles transports lactic acid to liver where converted back to glucose
• cardiovascular diease

  damages lining of arteries - build up fatty material - heart attack or stroke

  inhalation co2 = reduce o2 levels carried by blood

  nicotine = increased heart rate, puts strain on heart
• lung disease

  tobacco

  chemicals stop cilia in trachea and bronchi working

  no mucus, dirt, bacteria moved from lungs . airways swollen ,mucus build up

  breathless - more difficult to obtain oxygen reuqired
• lung cancer

  
  

  carcinogens in tar case cancer ny mutating cells
• alcohol effects on liver (liver rest for breakdown alcohol)

  damages , fats build up, alcohol hepatitis - death

  cirrhosis of liver - scarred cant function
• alcohol on brain

  not removed at liver - travels to Brian

  brain shrinkage , memory problems
• bypass surgery

  removes blocked arteries

  used where stents cant help

  major surgery

  anasethetuf

  risk of dying/heart attack
• coronary heart disease

  lead to heart attack - no 02 and glucose reach heart muscles to beat

  prevent by ;

  low fat diet

  to reduce cholesterol
• carbohydrate produced and acts

  salivary glands

  pancreas

  mouth

  small intestine
• protease produced and acts

  stomach

  pancreas

  small intestine

  stomach

  small intestine
• lipase produced and acts

  pancreas

  small intestine

  small intestine
• vascular tissue = xylem transport water to leaf

  phloem transport glucose to other parts
