Lucille is finding it difficult to play soccer after school. Her doctor thinks that her cells might not be getting enough oxygen. When Lucille talked about it with a friend, her friend said there might be a problem with Lucille’s respiratory system or circulatory system. What do Lucille’s cells need in order for her body to function properly? How might a problem with Lucille’s respiratory system or circulatory system make it difficult for Lucille to play soccer? HEL

Lucille needs oxygen and glucose in her cells in order to play soccer.  

Explanation:

Both oxygen and glucose are required for the cells to perform cellular respiration and metabolism which leads to energy or ATP molecules.

Glucose is the primary reactant in cellular respiration which leads to the production of energy molecules.

This energy is used to perform various voluntary and involuntary activities. It is this energy that empowers the muscles to perform activities like running, jumping, playing games like soccer, tennis, etc.  

Glucose enters the cells by circulating through the bloodstream

Oxygen inhaled by the nostrils passes through the respiratory system and is circulated throughout the body and carried to the cells through the circulatory system.

Hence, Lucille might be having a problem with respiratory or circulatory system.

Explanation:

The body's energy supply is met by the metabolism of glucose in cells using oxygen. The problem with Lucille's respiratory and circulatory system can make it difficult for her to take part in a soccer game because the needed energy would not be available for her to participate in the game.
