Answer:
Increased risk of bronchitis and emphysema - Respiratory system.
Explanation:
Prolonged use of tobacco can cause problems with the respiratory system and increase the risk of bronchitis and emphysema.
Bronchial inflammation is commonly referred to as bronchitis, but it is important not to confuse it with chronic bronchitis, a condition that causes cough and expectoration on most days for at least three months a year for two consecutive years.
Emphysema, in turn, is a chronic obstructive pulmonary disease caused by overexposure to pollutants and chemicals such as smoke and cigarettes. This causes the gradual destruction of the pulmonary alveoli. The alveoli are tiny air sacs located in the lungs at the end of the bronchioles. Outside these structures are networks of blood capillaries from the blood vessels of the small circulation.
