What carbon monoxide tar nicotine emphysema and brochitis?
1. Carbon monoxide: When cigarettes are burned, they release carbon monoxide, which is a poisonous gas. Carbon monoxide binds to hemoglobin in the blood, reducing the blood's ability to carry oxygen. This can cause headaches, dizziness, confusion, and even death in high doses.
2. Tar: Tar is a sticky, brown substance that is formed when cigarette smoke condenses. Tar contains many chemicals, some of which are known carcinogens. Tar accumulates in the lungs and can damage lung tissue, leading to respiratory problems such as bronchitis, emphysema, and lung cancer.
3. Nicotine: Nicotine is a highly addictive chemical that is found in cigarettes. Nicotine stimulates the central nervous system and can cause an increase in heart rate, blood pressure, and breathing. Nicotine also contributes to the development of dependence on cigarettes.
4. Emphysema: This is a chronic lung disease in which the air sacs in the lungs (alveoli) are damaged and lose their elasticity. This can cause shortness of breath, coughing, and wheezing. Emphysema is often caused by smoking cigarettes.
5. Bronchitis: It is an inflammatory condition that affects the bronchial tubes, the airways that carry air to and from the lungs. Acute bronchitis is usually caused by a viral infection, while chronic bronchitis is a long-term condition that is often caused by smoking cigarettes.
