Oh No! I need to hurry before I miss it the bus.
I just made it , thank goodness. I am so out of breath!
I am so glad I made it. Now my body needs to cool down from my muscles working.
When running the muscles in the leg for example the hamstrings demand a lot of blood to be able to have continuous movement.
During intense activity the heart which is apart of the circulatory system will supply the extra amount of blood needed in the body and also the blood will carry oxygen to the muscles.
When the body is at rest after physical activity blood carries needed nutrients to the muscles to repair them from running in this situation. This helps the heart and also the muscles to recover.
