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. the brain sends signals throughmotor neurons. sensory receptors in the arteries detect low oxygen levels. the central nervous system relays animpulse to certain brain regions. isabel's breathing rate increases.

The path way to regulate the low oxygen level in blood is;

Sensory receptors in the arteries detect low oxygen levels: First of all receptors near blood vessels detect low oxygen level.Sensory neurons generate an impulse: Then neurons generate the impulse of low oxygen level which moves to central nervous system.The central nervous system relays an impulse to certain brain regions: After reaching the impulse to central nervous system, another impulse is generated which is sent to corresponding regions of brain.The brain sends signals through motor neurons: A impulse of recovery is sent to lungs via motor neurons.Isabel's breathing rate increases: Blood in lungs get more oxygen by increasing breathing rate.

Idk i think the answer choice is number 1

Bis the answerhope it
