Keeping Healthy
1 Diet
1.1 Food Groups
1.1.1 Carbohydrates Release Energy
1.1.2 Fats Keep warm Release Energy
1.1.3 Protein Growth and Repair
1.1.4 Fibre Digestive System
1.1.5 Vitamins and Minerals Skin, bones and blood
1.2 Metabolism
1.2.1 Chemical reactions in the body Keep you alive
1.2.2 Metabolic Rate Speed chemical reactions occur in the body Higher muscle to fat ratio =Higher metabolic rate Exercise increases MR Bigger people have higher MR More Cells=More Energy Men have higher MR More muscle
2 Factors Affecting Health
2.1 Bad Diets
2.1.1 Obesity Excess carbs or fat=obesity Bad diet, overeating, lack or exercise, hormonal problems Athritis, type 2 diabetes, high blood pressure, heart disease, cancer
2.1.2 Too much sat fat High Cholesterol
2.1.3 Too much salt High blood pressure Heart Problems
2.1.4 Eat too little... Malnutrition Slow growth, fatigue, poor infection resistance Defieciency Diseases
2.2 Exercise
2.2.1 Increases body's energy
2.2.2 Decreases fat stores
2.2.3 Builds muscle, increases MR
3 Fighting Disease
3.1 Pathogens
3.1.1 Bacteria Small Cells Damage Cells Produce Toxins
3.1.2 Viruses Not Cells Replicate themselves Cell Damage
3.2 Defence System
3.2.1 Skin, hairs and mucus
3.2.2 Platelets Help blood clot to seal wounds
3.2.3 White Blood Cells Engulf & Digest Foreign Cells
3.2.4 Antibodies White blood cells find foreign antigens Produce antibodies to lock onto and kill invading cells Specific antibodies for each cell Reproduce rapidly, killing bacteria or viruses
3.2.5 Antitoxins Produced by invading bacteria
3.3 Vaccination
3.3.1 Inject small or inactive micro-organisms Body produces antigens to help them White blood cells can produce antibodies in future
3.3.2 Pros Controls diseases that we're once common in UK Epidemics prevented
3.3.3 Cons Don't always work Can have reactions
3.4 Antibiotics
3.4.1 Kill bacteria
3.4.2 Resistance Bacteria can Mutate Resistant strain- cause serious infection Over-prescribed
3.5 Antiseptics
3.5.1 Semmelweis Women not surviving childbirth Unwashed hands Bacteria Spreads
3.6 Antibiotic Resistance
3.6.1 Bacteria evolve it Antibiotic Overuse
