Covers the meaning of health and disease, communicable versus non-communicable diseases, and the role of pathogens such as bacteria, fungi, viruses and protists. Explains disease causes linked to lifestyle factors and failures within body systems. Includes worked data interpretation using an Ebola cases table, plus exam-focus guidance and questions, then extends to heart diseases, including coronary heart disease, faulty valves and heart failure, with evaluation and treatment options such as stents, statins and transplants.","Biology  \nOrganisation  \nHealth issues  \nHealth is the state of physical and mental wellbeing, including being free from disease. Disease is a disorder that has specific symptoms and is not caused by injury. You need to know about factors that can cause ill health.  \n Types of disease   \nDisease interaction   \nSome diseases are communicable and some are not.  \nCommunicable diseases  \nCommunicable diseases are diseases that can be spread  from one person to another. They are often called infectious diseases. They are caused by pathogens – microorganisms that cause disease. Examples of pathogens are:  \n○ bacteria ○ fungi  \n○ viruses ○ protists.  \nNon-communicable diseases  \nNon-communicable diseases are diseases that cannot be passed on from one person to another.   \nThey are usually caused by lifestyle factors, such as diet, stress, drinking and smoking, and/or failures within the body’s own systems, such as autoimmune diseases and old age.  \n10  Worked example  Grade 4   \nThe table shows some data on the number of cases of a disease called Ebola in an African country over a 6-week period.  \n| Week | 1 | 2 | 3 | 4 | 5 | 6 |\n| --- | --- | --- | --- | --- | --- | --- |\n| Number of cases of Ebola | 50 | 72 | 124 | 181 | 293 | 598 |\n\n(a) Which statement best describes the trend caused by the data?  \nTick one box. [1 mark]  \nThere was no change in the number of  \nEbola case over the 6 weeks. The number of Ebola cases increased slightly between week 1a nd 6.  \nThe number of Ebola cases increased considerably between week 1a nd 6. The number of Ebola cases decreased between week 1a nd 6.  \n(b) Explain whether the disease is communicable  \nor non-communicable [2 marks]  \nIt is communicable, because it spreads by contact between people.  \nSome diseases may be caused by more than one factor.  \n○ Defects in the immune system mean a person is more likely to su􀀞er from infectious diseases.  \n○ Viruses living inside cells can sometimes trigger cancer. Cancer is the result of changes in cells that lead to uncontrolled growth and division.  \n○ Immune reactions initially caused by a pathogen can trigger allergies such as skin rashes and asthma.  \n○ Severe illnesses can lead to mental illnesses, including depression.  \nExamples include flu, measles and food poisoning.  \nExamples include cardiovascular diseases, some cancersand diabetes.  \n1  Exam focus     \nIn the exam, you could be expected to interpret data from a table, graph or chart. Before answering any questions, make sure you know what the data are, what the units are, and if there are any trends.  \n10 Exam-style practice  Grade 5   \n1 State what is meant by a ‘pathogen’. [1 mark]  \n2 Give two examples of pathogens. [2 marks]  \n3 The influenza virus can be carried in droplets in  \nthe air. Suggest how an infected person could infect someone else sitting nearby. [2 marks]  \nMade a start  \n Feeling confident  \n Exam ready  \n21  \nBiology Organisation  \nCoronary heart disease  \nCardiovascular disease (CVD) involves the heart or blood vessels. It includes coronary heart disease (CHD) . You need to know how di􀀞erent diseases of the heart occur and how they can be treated.  \n10 Diseases of the heart   \nBlocked coronary arteries  \nThe coronary arteries supply the heart muscle cells with blood containing oxygen and glucose.  \nThe build-up of fatty deposits in the coronary arteries is related to high blood cholesterol levels. The deposits can narrow or even block arteries, starving the heart muscle of oxygen. This can cause a heart attack, when the heart stops beating.  \nFaulty valves  \nThe valves in the heart prevent blood from flowing backwards when the muscles of the heart contract. Sometimes the valves in the heart become faulty, preventing the valve from opening fully, or the valve may develop a leak. This makes it harder for the heart to pump blood around the body.  \nHeart failure  \nHeart failure occurs when the heart is unable to pump  blood around the body properly.  \nGo to page 20 for more ab","cbCaidajZZlNuVTw","https://ap.wps.com/l/cbCaidajZZlNuVTw","pdf",1458662,1,6,"English","en",105,"# Biology\n## Health issues\n## Types of disease\n## Disease interaction\n## Worked example: Ebola cases trend\n## Exam focus and practice\n## Coronary heart disease\n## Diseases of the heart\n## Evaluation of treatments\n## Treating blocked coronary arteries\n## Treating faulty valves\n## Treating heart failure\n## Treatment practice: stents and statins","[{\"question\":\"What is meant by health and disease in this guide?\",\"answer\":\"Health is physical and mental wellbeing, including freedom from disease.
