Answer:
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.
