1. Breathing control centre are:
- found in the carotid artery in the neck.
6. In the blood plasma:
- CO2 released by cellular respiration
- reacts with H2O to form carbonic acid (H2CO2)
- increase in hydrogen ions (H+) conc.
- increase the acidity of the blood plasma,
8. When blood flows through Peripheral Chemoreceptors (from aortic + carotid bodies) + Central Chemoreceptor
à sends impulses (via parasympathetic nerve) to the diaphragm + external intercostals muscle
