Station 1: Sierra is running in a school track meet. She will need extra energy to complete
the race and her body systems need to work
together to help her get it. Cellular respiration
is the way our bodies get energy out of the food
we eat. Her body needs to make sure her cells
get enough oxygen for cellular respiration to
occur but removes the carbon dioxide that is
built up in this same process. Which body systems will work together to
maintain the energy Sierra needs?​
