Why is it necessary for your pulse/heart rate to increase when you become more active?

• Our heart has to work less to send less oxygen and nutrients to the cells to make energy

• Our heart has to work harder to send more oxygen and nutrients to the cells to make energy

• Our heart has to work harder to send more CO₂ and waste to the cells to make energy

• Our heart has to work less to send more CO₂ and waste to the cells to make energy

How would an athlete's lung capacity differ from an non-athletes?

• An athlete would have a smaller lung capacity because they don't have to use their lungs as much as a non-athlete.

• An athlete would have a larger lung capacity because they use their lungs more and need more oxygen during activities than non-athletes.

• An athlete would have the same sized lung capacity because they don't do anything different than non-athletes and need the same amount of oxygen.

• An athlete would have a larger lung capacity because they don't have to use their lungs as much as a non-athlete.
