EXERCISE
Basically, when we exercise our muscles need more energy to work. Energy is created during respiration, and we need oxygen for respiration. Carbon dioxide is produced during respiration, so if there is more respiration occurring, there will be more carbon dioxide produced, so the heart needs to increase its speed so that more blood, which is carrying oxygen which will be sent to the muscles (it will also carry away the deoxygenated blood). Carbon dioxide is no good for respiration!

Adrenaline is a hormone, so it is carried around in the plasma part of your blood (see post on plasma) which is yellow. As mentioned above, it is produced in the adrenal gland.
