Side A ------ Side B
1.Respiratory syst. made up of... ------ -
and... ------ -
2.Breathing mechanism ------ Inhalation:-thoraric cavity-bigger
                  -air pressure in lung-lowered
                  -air force into lungs
Exhalation:-thoraric cavity-smaller
                      air pressure in lung-increased
                      -air forced out of lung
3.Transport of oxygen ------ -oxygen dissolve in alveolus,then diffuse into 
blood capillaries
-the blood contain red blood cell which rich with haemoglobin
-oxygen+haemoglobin=oxyhaemoglobin
-the blood leave lung and carried to the heart,then disstribute to all pats of body
4.Effects of harmful substances:
a)Cigarette smoke ------ contain:tar-cause lung cancer
              nicotine-cause addiction to smoking
              carbon monoxide-reduce oxy. in blood
b)car exhaust ------ contain: carbon monoxide-reduce oxy. in blood
c)Industry and vehicles ------ contain:sulphur dioxide-damage lung tissues
              hydrocarbons-cause cancer
              nitrogen oxide-interacts with
              hydrocarbons to form haze
 
5.Diseases that affect respiratory system ------ -bacteria,virus&micoorganisms produce toxins in human body which cause illness
-virus-cause influenza and whooping cough or
 pneumonia
-asbestos dust is a carcinogen which cause lung cancer
9.Ways to improve quality of air ------ a)stop smoking
b)use air cleaning system to dissolve toxic gases
   like sulphur dioxide in water before released
   into atmosphere
c)install catalyst convertors on vehicle exhaust pipe to reduce dangerous gases like carbon monoxide
