Why and How does running speed affect pulse rate?

please could you be more specific with the why rather than the how, and quite an in depth answer for why running speed affects pulse rate, thanks! will give lots of points!

Your joints and body parts are moving faster than usual. So the heart has to pump more oxygen than usual through your blood. That is why we often breathe faster while running after running than when we are walking. The heart pumps blood and oxygen through our bodies by pulsing. The more it needs to pump, the faster it pulses. That is also why when you are out of breath, your heart is pulsing faster.

    Increased heart rate in running during learning the Pose Method technique is a very common occurrence and it brings up many questions about this matter. Why does the heart rate go up? Is it a normal thing? When does it come back to normal? How does this increased heart rate affect our training in the Pose Method of running?
