FAQs on Infographics: Respiratory System - Science Class 10

1. What are the main functions of the respiratory system?
Ans. The main functions of the respiratory system include the exchange of gases (oxygen and carbon dioxide) between the body and the environment, regulation of blood pH, and facilitating the sense of smell. It also helps in producing sound through the vocal cords located in the larynx.
2. How does the respiratory system work?
Ans. The respiratory system works by taking in oxygen through inhalation, which travels through the trachea and into the lungs. In the lungs, oxygen is exchanged for carbon dioxide in tiny air sacs called alveoli. The carbon dioxide is then exhaled back into the environment, completing the respiratory cycle.
3. What are the common diseases affecting the respiratory system?
Ans. Common diseases affecting the respiratory system include asthma, chronic obstructive pulmonary disease (COPD), pneumonia, bronchitis, and lung cancer. These conditions can affect breathing and overall lung function, often leading to severe health complications if not managed properly.
4. How does smoking impact the respiratory system?
Ans. Smoking significantly harms the respiratory system by damaging the airways and lung tissue. It leads to reduced lung function, increased risk of respiratory diseases, and contributes to the development of conditions like emphysema and lung cancer. Quitting smoking can help improve respiratory health over time.
5. What can be done to maintain a healthy respiratory system?
Ans. To maintain a healthy respiratory system, it is important to avoid smoking, engage in regular physical activity, practice good hygiene to avoid infections, and ensure proper indoor air quality. Eating a balanced diet rich in antioxidants and staying hydrated can also support respiratory health.
