Question

Name the chronic respiratory disorder caused mainly by cigarette smoking.
a. Respiratory alkalosis
b. Emphysema
c. Asthma
d. Respiratory acidosis

Answer 1

Hint: Smoking causes the alveoli sacs to weaken or become thin, making them unable to exchange oxygen and carbon dioxide efficiently, resulting in erratic breathing and heart rate owing to a shortage of oxygenated blood in the systemic circulation.

Complete step by step answer:
The most common disease caused by cigarette smoking is a chronic obstructive pulmonary disease, also known as COPD. This disease commonly causes shortness of breath and coughing, which is why it is often called a smoker's cough. Chronic Obstructive Pulmonary Disease (COPD) is a chronic respiratory disorder caused mainly by cigarette smoking. COPD is also called chronic obstructive lung disease, or chronic airflow limitation if there is no reversibility of the obstruction. COPD is a chronic respiratory disorder caused mainly by cigarette smoking.
COPD is a chronic respiratory disorder that develops over time and is caused mainly by smoking cigarettes. It has been observed in research that COPD is responsible for more than 3 million deaths every year and it is one of the most common lung diseases known. COPD is a chronic disease that affects the lungs by causing shortness of breath, wheezing, and extreme coughing. COPD is caused by damaged or narrowed airways in the lungs. Emphysema can lead to COPD as it does not allow for sufficient air to flow into your lungs. COPD can also be caused by other lung diseases such as pneumonia or bronchitis. Option B is the correct answer.

Additional Information : The term COPD is an amalgamation of the phrases chronic obstructive pulmonary disease, from the Latin word "Pulmo", meaning lung, and the English word "disease". Chronic Obstructive Pulmonary Disease (COPD) is an umbrella term for several lung conditions, including chronic bronchitis and emphysema. These disorders can damage the lungs and make it difficult to breathe.

Note: COPD is a serious lung disease that shares some symptoms with Emphysema. COPD is a chronic illness, which means it lasts for years or even decades. COPD can cause shortness of breath, weakness, fatigue, and lack of appetite.
