- The body transitions from a period of rest, to a period of physical activity, which increases the need for oxygen, and energy.
- There is an increase in physical activity, therefore there is a need to increased energy, and therefore, oxygen.
- There is much lower air pressure in high altitudes, so there is a need to breathe faster due to less air in the surroundings.
- The phrenic nerve is responsible for the contraction of the diaphragm. When it is damaged, one side of the diaphragm is elevated, and cannot move, so the other side has to compensate for the lack of air.
- Since Red Blood Cells carry Oxygen, a decrease in Red Blood Cells therefore result in less oxygen in the body, warranting the need to breathe faster.
- Since the mother needs to sustain the fetus, there is a need for her to breathe faster to provide oxygen to both herself, and the fetus.
