Stroke Volume 7 of 24 The heart becomes bigger and stronger, meaning it can supply the same amount of blood in fewer beats. Decreased resting Heart Rate 8 of 24 The heart can return to its normal rate after exercise quicker than it used to be able to. Quicker heart recovery rate 9 of 24 More blood is pumped by the heart every week, making it more efficient and stronger. This also leads to increased cardio output Increased Stroke Volume 10 of 24 The heart is more efficient and stronger as a result of exercise. Reduced Blood Pressure 11 of 24 Blood vessels are more flexible and efficient and so stay clear as well as increasing the number of capillaries in the heart Healthier veins and arteries 12 of 24 Where gas exchange takes place Capillaries 13 of 24 A fatty substance carried in the blood by lipoproteins Cholesterol 14 of 24 Contains more proteins than fat and carries the cholesterol away from the heart and to the liver where it is removed from the body High Density Lipoproteins 15 of 24 Consists mainly of fats and can lead to a build-up of plaque in the blood and can restrict the blood flow to the arteries Low Density Lipoproteins 16 of 24 Raises blood pressure because they release adrenaline. Nicotine in cigarettes 17 of 24 Constricts the arteries and causes the heart to beat faster Adrenaline 18 of 24 Lowers HDL and increases the tendency for blood to clot. Smoking 19 of 24 These can lead to serious problems such as heart attacks or strokes. Blood Clots 20 of 24 Long-term abuse of this can lead to the lowering of blood pressure Alcohol 21 of 24 The long-term benefits of the cardiovascular system resulting from regular exercise Decreased resting heart rate, Quicker heart recovery rate, Increases stroke volume, Reduced blood pressure, Healthier Veins and Arteries 22 of 24 The two forms of Lipoproteins HDL and LDL 23 of 24 The effects of recreational drugs on the cardiovascular system Nicotine in cigarettes, Smoking and Alcohol 24 of 24
