They need more oxygen to function, so gas exchange needs to increase.

As Kristen began the physical exercise, the workload of her muscles became higher, which yielded a greater need of ATP. So as to yield ATP, the mitochondria needs higher amount of oxygen and glucose to produce the ATP molecules, which will in turn raises the need for oxygen. The aftermath of the need for higher oxygen results in the lungs undergoing more gaseous exchange, in order to meet this high oxygen need.
