FAQs on Frog: Respiratory & Nervous Systems Video Lecture - Biology for Grade 11
| 1. What is the respiratory system of a frog? |  |
Ans. The respiratory system of a frog consists of lungs and skin. Frogs have a specialized breathing process called cutaneous respiration, where oxygen is absorbed through their thin and moist skin. They also have lungs to supplement their oxygen intake.
| 2. How does the respiratory system of a frog work? | |
Ans. In a frog, the respiratory system works by a combination of breathing through the skin and lungs. When a frog is on land, it breathes using its lungs by inhaling air through its nostrils. However, when in water, it relies more on cutaneous respiration, where oxygen diffuses through the skin into the bloodstream.
| 3. What is the role of the nervous system in a frog? | |
Ans. The nervous system in a frog is responsible for coordinating and controlling its body's functions. It includes the brain, spinal cord, and nerves. The nervous system receives and processes sensory information, sends signals to muscles for movement, and regulates various physiological processes in the frog's body.
| 4. How does the nervous system in a frog work? | |
Ans. The nervous system in a frog works through a network of neurons that transmit electrical signals. Sensory receptors detect stimuli from the environment, such as touch or light, and send signals to the brain and spinal cord. The brain processes the information and sends appropriate signals to muscles for a response or initiates hormonal changes to regulate bodily functions.
| 5. How does the respiratory and nervous systems of a frog interact? | |
Ans. The respiratory and nervous systems of a frog have a close interaction to ensure efficient oxygen intake and survival. The nervous system controls the frog's breathing rate and depth, allowing it to adjust its respiration based on the oxygen demand. The nervous system also coordinates the muscles involved in respiration, such as the diaphragm, to facilitate proper lung function. Additionally, the nervous system helps regulate the frog's body temperature, which affects its respiratory rate and metabolism.
