1. Sensory receptors in the arteries detect low oxygen levels. 2. Sensory neurons generate an impulse. 3. The central nervous system relays an impulse to certain brain regions. 4. The brain sends signals through motor neurons. 5. Isabel's breathing rate increases.
During Isabel's marathon, her body's intricate regulatory system responds to the increased demand for oxygen. As she nears the finish line, sensory receptors in her arteries detect low oxygen levels. These receptors send signals via sensory neurons, creating an impulse. The central nervous system then relays this impulse to specific brain regions, where the information is processed.
Subsequently, the brain initiates a response by sending signals through motor neurons. Finally, these signals reach the muscles involved in breathing, prompting an increase in Isabel's breathing rate. This intricate coordination showcases the body's ability to dynamically adjust to changing conditions, ensuring oxygen supply meets the heightened demand during strenuous physical activity.
The complete question is:
The body monitors the levels of oxygen in the blood to regulate breathing. Isabel is running in a marathon and is near the finish line. She feels out of breath. How will her nervous system work to generate a reaction? Arrange the tiles in chronological order.
Isabel's breathing rate increases.
The central nervous system relays an
impulse to certain brain regions.
Sensory neurons generate an impulse.
Sensory receptors in the arteries
