Whew! Only 1 more mile to run after this break and i'm done for the day!
Did you know that when you start running again, your circulatory system will provide your muscles with the oxygen and nutrients your muscles need so that your muscles have the energy they need?
As Tanner is running his lungs are bringing oxygen to the body which provides energy and his lungs are also eliminating carbon dioxide. Tanners heart pumps the oxygen into his muscles that are working during the excercise.
Really?!? I didn't know that..
Now that Tanner is relaxing after his exercise his muscles are relaxing more than they were when he was running.
Yup! And while your excercising more blood is being sent back to your heart because the muscles are squeezing blood in your veins.
Tanner is learning new things about his body that he didn't know before.
Well thanks for telling me those interesting facts but I gotta run!!
