The correct response is:

**The cells throughout the body used the oxygen.**

When blood circulates through the body, oxygen is delivered to the tissues and cells, which use it for cellular respiration and energy production. This process depletes the oxygen content of the blood, resulting in the blood returning to the heart having low oxygen levels.
