It increases blood pressure and heart rate. Not only these, smoking increases tendency for the blood to clot. It reduces the capacity of a person to exercise.
- Lungs: smoking destroys small hairs present in upper parts of airways. In normal persons these hairs protect lungs from germs, dust and other harmful particles. When this natural cleaning system is damaged germs, dust, smoke and other harmful chemicals enter lungs causing infection, cough and lung cancer. The air sacs of lungs (alveoli) get permanently damaged causing difficulty in breathing.
