FAQs on Breathing in Cockroach Video Lecture - Science Class 7 (Old NCERT)
| 1. How do cockroaches breathe? |  |
Ans.Cockroaches breathe through a system of tubes called tracheae, which deliver oxygen directly to their tissues. They have small openings on their bodies, called spiracles, that allow air to enter these tubes.
| 2. Can cockroaches hold their breath? | |
Ans.Yes, cockroaches can hold their breath for extended periods. They can survive without oxygen for about 30 minutes by closing their spiracles, which helps them endure low-oxygen environments.
| 3. Do cockroaches breathe through their mouth? | |
Ans.No, cockroaches do not breathe through their mouths. They breathe through spiracles located on the sides of their bodies, allowing air to flow directly into their tracheal system.
| 4. How does a cockroach's breathing system compare to that of humans? | |
Ans.Cockroaches have a more efficient breathing system for their size compared to humans. While humans use lungs to exchange gases, cockroaches use a network of tracheae that delivers oxygen directly to their cells, allowing for rapid oxygen absorption.
| 5. What happens to a cockroach if it is deprived of oxygen? | |
Ans.If a cockroach is deprived of oxygen, it can become lethargic and may eventually die if the oxygen deprivation continues for too long. However, they are quite resilient and can survive in low-oxygen environments longer than many other insects.
