Mr Leonard running late for class and decides to sprint down the stairs so he can arrive on time. As he runs, he needs to maintain a steady supply of oxygen, nutrients, and water to his muscles, and also remove waste products like carbon dioxide and lactic acid.

Question:
Explain how the circulatory, respiratory, and muscular systems interact to meet the needs of his cells as he runs.
