Answer:
Some diseases caused by smoking:
- Cancer of the mouth and throat, oesophagus / esophagus, stomach, colon, rectum, liver, pancreas, voice box (larynx), trachea, bronchus, kidney and renal pelvis, urinary bladder, and cervix.
Step-by-step explanation:
Heart Disease: A person's arteries might get blocked as a result of smoking. This prevents proper blood flow, which might result in a heart attack or stroke.
Emphysema (a lung disease): The lungs' alveoli are damaged by the chemicals in tobacco smoke. Their walls weaken, and when you breathe in, they don't properly inflate. Coughing may cause them to explode. As a result, less oxygen is transported through the bloodstream, which causes shortness of breath.
Respiratory Infections: Mucus is produced by the cells in your trachea, which serves as a filter for dust and bacteria. Moreover, your airways are kept clear by cilia, which push mucus into your stomach. The cilia are prevented from moving by chemicals in tobacco smoke. This allows for mucus to enter your lungs, which makes breathing difficult and frequently results in infections. Smokers cough this mucus up, which can harm the lungs further.
Cancers: At least 70 of the over 5000 chemicals released by cigarette smoke can cause cancer. In our lungs, the dangerous chemicals spread throughout our entire body. DNA is harmed by cigarette chemicals. Cells have a tougher time repairing any DNA damage due to the chemicals in cigarettes. Moreover, they harm the DNA that guard against cancer. Cancer is brought on by the build-up of genetic damage in a cell over time.
