Answer:

When Kristen is running and her breathing rate increases, the statement that best describes how her tissues are responding to her running is that they need more oxygen to function, so gas exchange needs to increase.

Explanation:

Options for this question are:

  • They need more oxygen to function, so gas exchange needs to decrease.
  • They need more oxygen to function, so gas exchange needs to increase.
  • They need more carbon dioxide to function, so gas exchange needs to increase.
  • They need more carbon dioxide to function, so gas exchange needs to decrease.

Physical activity in a person requires an adequate supply of nutrients and oxygen to the tissues, to ensure the production of energy in the form of ATP, obtained from cellular respiration.

A physical exercise implies an increase in the skeletal muscle's ATP demand, so both glucose and oxygen consumption will be higher, which implies an increase in breathing rate to increase lung gas exchange and oxygen bioavailability.
