Algorithms have been developed to systematically determine the skeleton of the underlying graph and, then, orient all arrows whose directionality is dictated by the conditional independencies observed. In general this leaves a set of possible causal relations, which should then be tested by analyzing time series data or, preferably, designing appropriately controlled experiments. In contrast with Bayesian Networks, path analysis and its generalization, structural equation modelingserve better to estimate a known causal effect or to test a causal model than to generate causal hypotheses.
Carbon monoxide is found in car exhaust fumes and is fatal in large doses. It replaces oxygen in the blood and starves organs of oxygen and stops them being able to function properly. Tar is a sticky, brown substance that coats the lungs and affects breathing.
Smoking affects many different areas of the body. Below, we cover each part of the body in turn: Brain Smoking can increase the likelihood of having a stroke by 2 to 4 times.
Strokes can cause brain damage and death. One way that stroke can cause brain injury is through a brain aneurysmwhich occurs when the wall of the blood vessel weakens and creates a bulge. This bulge can then burst and lead to a serious condition called a subarachnoid hemorrhage.
Bones Smoking can make bones weak and brittle, which is particularly dangerous for womenwho are more prone to osteoporosis and broken bones. Cardiovascular system Smoking causes plaque to build up in the blood. Plaque sticks to the walls of arteries atherosclerosismaking them narrower; this reduces blood flow and increases the risk of clotting.
Smoking also narrows the arteries, making it harder for blood to flow, as well as increasing blood pressure and heart rate. Also, chemicals in tobacco smoke increase the chance of heart problems and cardiovascular diseases.
Some of the most common are: Coronary heart disease - narrow or blocked arteries around the heart. It is among the leading causes of death in the U.
Heart attack - smokers are twice as likely to have a heart attack. Carbon monoxide and nicotine in cigarettes make the heart work harder and faster; this means that smokers will find it more difficult to exercise. Even smokers who smoke 5 or fewer cigarettes a day can have early signs of cardiovascular disease.
Immune system The immune system protects the body against infection and disease. Smoking has also been linked to type 2 diabetes. Lungs Smoking can cause a variety of lung problems.Asbestos exposure and smoking can each cause lung cancer and other serious diseases.
However, the combination of the two risk factors multiplies the hazard, creating a greater health risk. Review the section on Clustering and Outlining to see how one student writer began to gather thoughts about a paper on the effects of the weather phenomenon known as El Niño.

We also offer a few examples as guides. Smoking is considered as a slow way of death. For example, it causes emphysema that slowly but continuously effects lungs. The effect of emphysema is repeated attacks of bronchitis, lung-diseases and heart failure.
Nicotine in blood causes shortage of oxygen in the human body which, in turn, exerts pressure on heart.
