FAQs on Cockroach: Respiratory & Nervous Systems Video Lecture - Biology Class 11 - NEET
| 1. What is the respiratory system of a cockroach? |  |
| 2. How does the respiratory system of a cockroach differ from that of humans? | |
Ans. Unlike humans, cockroaches do not have lungs. Instead, they rely on the tracheal system to transport oxygen directly to their cells. This allows for a more efficient exchange of gases, as oxygen travels directly to the cells without the need for a circulatory system.
| 3. How does the nervous system of a cockroach function? | |
Ans. The nervous system of a cockroach consists of a brain, segmented ganglia, and a network of nerves throughout the body. The brain receives sensory information from the environment and sends signals to the ganglia, which are responsible for coordinating various functions such as movement and digestion.
| 4. How do cockroaches sense their environment? | |
Ans. Cockroaches have sensory organs called sensilla located on their antennae, legs, and mouthparts. These sensilla detect various stimuli such as touch, temperature, humidity, and chemical signals. The information gathered by these sensory organs is transmitted to the brain, allowing the cockroach to perceive and respond to its environment.
| 5. Can cockroaches survive without their respiratory or nervous systems? | |
Ans. No, cockroaches cannot survive without their respiratory or nervous systems. The respiratory system is essential for delivering oxygen to their cells and removing waste gases like carbon dioxide. The nervous system controls all vital functions and allows the cockroach to respond to stimuli. Without these systems, the cockroach would not be able to survive.
