I know that chemoreceptors regulate blood pressure by monitoring the levels of H, O2 and CO2 in the blood, but why and how do these chemicals effect blood pressure?

I know that if too much CO2 and H is found in the blood by chemoreceptors, the medula oblongata will cause vasodialation (or constriction if there is too little im guessing) along with a slower heart rate.  But how and why do these chemicals effect the blood pressure?
