FAQs on How do we Breathe? Video Lecture - Science Class 7 (Old NCERT)
| 1. How does the process of breathing work? |  |
Ans. When we inhale, the diaphragm contracts and moves downward, creating more space in the chest cavity. This allows air to rush into the lungs. When we exhale, the diaphragm relaxes and moves back up, pushing air out of the lungs.
| 2. What is the role of the respiratory system in breathing? | |
Ans. The respiratory system includes the lungs, diaphragm, and other organs involved in the process of breathing. These organs work together to take in oxygen from the air and remove carbon dioxide from the body.
| 3. Why is proper breathing important for overall health? | |
Ans. Proper breathing helps ensure that our bodies receive enough oxygen to function properly and remove waste gases like carbon dioxide. It also helps reduce stress, improve focus, and promote relaxation.
| 4. What are some common breathing exercises that can help improve lung function? | |
Ans. Some common breathing exercises include diaphragmatic breathing, pursed lip breathing, and box breathing. These exercises can help strengthen the respiratory muscles and improve lung capacity.
| 5. How can smoking and pollution affect our breathing? | |
Ans. Smoking and exposure to pollution can damage the lungs and respiratory system, leading to conditions like chronic obstructive pulmonary disease (COPD) and asthma. It is important to avoid smoking and minimize exposure to pollutants to maintain healthy breathing.
