FAQs on Human Respiratory System - NEET

1. What is the function of the human respiratory system?
Ans. The human respiratory system is responsible for the exchange of oxygen and carbon dioxide in the body. It helps in the process of respiration, which involves inhaling oxygen and exhaling carbon dioxide. This system ensures that oxygen is delivered to the body's cells and removes waste gases from the body.
2. How does the human respiratory system work?
Ans. The human respiratory system consists of the nose, trachea, bronchi, and lungs. When we breathe in, air enters through the nose and passes through the trachea into the lungs. The air then travels through smaller tubes called bronchi and bronchioles, eventually reaching the alveoli. In the alveoli, oxygen from the air is transferred into the bloodstream, while carbon dioxide is released from the bloodstream into the alveoli to be exhaled.
3. What are the main organs of the human respiratory system?
Ans. The main organs of the human respiratory system are the lungs. The lungs are a pair of spongy organs located in the chest cavity. They are responsible for the exchange of oxygen and carbon dioxide. The lungs are composed of bronchi, bronchioles, and alveoli, which are small air sacs where the exchange of gases takes place.
4. What are some common respiratory system disorders?
Ans. Some common respiratory system disorders include asthma, chronic obstructive pulmonary disease (COPD), pneumonia, bronchitis, and lung cancer. Asthma is a condition where the airways become inflamed, leading to difficulty in breathing. COPD is a group of lung diseases that make it difficult to breathe. Pneumonia is an infection in the lungs, while bronchitis is the inflammation of the bronchial tubes. Lung cancer is the abnormal growth of cells in the lungs.
5. How can we keep our respiratory system healthy?
Ans. To keep the respiratory system healthy, it is important to avoid smoking and exposure to secondhand smoke, as smoking damages the lungs and increases the risk of various respiratory disorders. Regular exercise can also help improve the functioning of the respiratory system. Maintaining good indoor air quality, practicing good hygiene, and getting vaccinated against respiratory infections like influenza can also contribute to a healthy respiratory system. Additionally, avoiding exposure to pollutants and practicing deep breathing exercises can help keep the respiratory system in good condition.
