Question

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.
Sensory neurons generate an impulse.
Isabel's breathing rate increases.
The central nervous system relays an
impulse to certain brain regions.
The brain sends signals through
motor neurons.
Sensory receptors in the arteries
detect low oxygen levels.

Answer 1

Reflex action refers to the response to a stimulus, while reflex arch refers to the path taken by the reflex action.

What is the nervous system?

1. Low oxygen levels are detected by sensory receptors in the arteries.

2. An impulse is produced by sensory neurons.

3. Certain parts of the brain get an impulse from the central nervous system.

4. Motor neurons carry messages from the brain.

5. Isabel's respiration becomes more rapid.

Reflex actions are immediate, reflexive reactions to stimuli that limit bodily harm.

Therefore, it travels to the brain via the central nervous system and sends impulses via Isabel's motor neurons, which aid to speed up her breathing.
