Beta-1 receptors are found in the heart, and when stimulated will increase herat rate and cardiac contractility. Beta-2 receptors are found on vascular smooth muscle located in the heart and skeletal muscle, and when they are activated, they dilate and decrease SVR.
The regulation of breathing is based in the body's acid/base balance. The Central Chemoreceptors (CCR), primarily responsible for the breathing stimulation, are affected by the PaCO2. The responsiveness of the peripheral receptors is tied to the level of pH and PaCO2. Together these provide the ultimate in servo-control - sensors provide feedback that increase or decrease breathing.
