Cardiovascular, cancer, nicotine  Key word Cardiovasc Cardiovascular refers The risk of certain ular to the heart (cardio) cardiovascular diseases and the blood vessels may be increased by (vascular). smoking, high blood pressure, high cholesterol, unhealthy diet, lack of exercise, and Show me…… obesity. 1) Cardiovascular refers to the stomach and lungs 2) The arteries, veins and capillaries are part of the cardiovascular system 3) The brain is part of the cardiovascular system The lungsprior Activating are an important organ in our gas exchange system knowledge:  What is the role of the gas exchange system?  What is exhaling and inhaling? Activating prior knowledge:  Activation & check of prior knowledge: The lungs are an organ where gas exchange happens TRU The lungs are where all respiration in the body E FAL happens In inhalation: air passes through the trachea, SE through the bronchioles, through the bronchi into FAL the alveoli SE FAL In inhalation: air passes through the trachea, through the bronchi, through the alveoli into the SE bronchiole FAL The bronchi are where gases are exchanged between the blood and the air SE CHALLENGE: Correct any false statements.  The UK government has invested millions in public health campaigns to reduce the amount of smokers in the UK.  This is because treating diseases caused by smoking still costs the NHS over 2.6 billion pounds a year Smoking is a very difficult habit to change as cigarettes contain the addictive chemical nicotine.

Cardiovascular disease  1. Cardiovascular disease is a disease of the heart a) heart b) lungs c) brain 2. Smoking causes _________ to build up in _______. a) tar, arteries b) fatty fatty deposits, deposits,arteries arteries c) tar, veins d) fatty deposits, veins 3. This _________ blood flow so heart cells can’t get enough __________ and start to die reduces, oxygen a) reduces, oxygen b) increases, oxygen c) reduces, water d) increases, water CHALLENGE: Explain why patients with cardiovascular disease will usually feel  Substances in cigarette smoke attack the DNA inside lung cells This causes DNA to mutate.  Mutations in DNA causes cells to multiply rapidly forming a tumours within the lungs  These tumours (maligent tumours) are what we call cancer.  If not treated early cells from these tumours can split of and form new tumours in other places around the body cancer Smoking can cause mutation. What does smoking cause mutations to? 1) The lungs 2) tumours 3) cells 4) DNA Smoking can cause mutation which leads to a tumour. What is a tumour? 1) A lump of cells infected with a 2) A rapidly multiplying lump of pathogen cells 3) A lump of material called 4) All of the above answers is cancer correct  If an individual continues to smoke while pregnant there are additional risks to the unborn child.  Substances from cigarettes can pass from the mother into the unborn child across an organ called the placenta.  One substance in particular – carbon monoxide – can really reduce the baby's growth. Carbon monoxide stops red blood cells carrying enough oxygen to the baby.  As well as reducing the growth of the baby smoking increases the risk of miscarriage. A miscarriage is when the pregnancy is lost. Placenta Carbon monoxide  How does smoking effect health? The statements are about smoking.
