You too many Qs expecting us all to give you the answers. Why don't you explain what you know and what confuses you and then we can help.

I don't think TSR users are going to want to spoon feed you all the answers.

I'll keep this as simple as I can; Chemoreceptors in the Aorta, carotid artery and the respiratory centre (medulla oblongata) detect pCO2 and pO2 (P=partial pressure) of the blood stream.
In response to higher/lower levels of CO2/O2, nerve impulses stimulate the respiratory muscles (diaphragm and the intercostal muscles) and thus increase/decrease the hypoxic drive. In doing so the rate of alveolar ventilation (the rate in which gas is exchanged in the alveoli of the lungs during breathing) is increase/decreased.
