- - - - build up of fatty deposits that form a hard plaque on the arterial walls
        
        reduces the space for blood flow and increases the likelihood of blood clots forming
        
        the arterial walls become thick and hardened meaning they struggle to vasodilate and constrict
        
        high blood pressure can form over time which is the first indicator
    - - this results from atherosclerosis of the arteries which supply the heart muscle with oxygenated blood
        
        there is a reduction in blood flow and oxygen supply is limits the cardiac muscles ability to respire or a heart attack can occur
    - - occurs when a piece of fatty plaque breaks away from an arterial wall causing a blood clot to potentially form
        
        if the clot suddenly, totally blocks a coronary artery it will cut off the oxygen supply which means cells will die and there is permanent damage
    - - caused by either a blockage in a cerebral artery cutting off the blood supply to the brain or a blood vessel bursting within or on the surface of the brain
    - - having a sedentary lifestyle is the major risk factor for CHD
        
        exercise can reduce the overall risk of developing some forms of cardiovascular diseases
      - regular training can:
        
        reduce the levels of blood fats and overall cholesterol
        
        increase blood flow and oxygen transportation to the muscle cells
        
        decrease body fat and help to manage weight which will reduce the strain on the heart
  - - - characterised by constriction of the bronchial airways and inflammation of the mucous membranes which restricts the airways and limits breathing
        
        symptoms = shortness of breath, wheezing and coughing
        
        this can happen cause of the drying of the airway membranes and presence of an allergens such as pollen or dust etc
        
        it can also be exercise induced meaning that the air is cold and dry causing symptoms of asthma
    - - a term for serval conditions of the lungs where the airways become inflamed and narrow
        Over time permanent changes are made:
        
        thickening of the bronchiole walls
        
        increased mucus production
        
        damage to the alveoli
        
        decrease in lung tissue elasticity
    - - smoking is the biggest risk factor for developing an respiratory disease
        
        sedentary lifestyles also increases the risk of infection
      - regular training can:
        
        increase respiratory muscle strength which alleviates the symptoms of asthma
        
        increase the surface area of the alveoli and pulmonary capillaries maximising the efficiency of gaseous exchange
        
        maintain full use of lung tissue and elasticity, decreasing the risk of infection
