Answer 2

Oxygen is important to blood and the cells for the metabolism to happen in our body.

Explanation:

• The blood transports $O_{2}$ from the lungs to the cells of the body, where it is further needed for metabolism
• Each cell needs oxygen for metabolism, which creates $CO_{2}$ as a waste product.
• Haemoglobin in the red blood cells carries oxygen around our body.
• Blood oxygen level is the measure of how much oxygen red blood cells are carried through arteries.
• Low blood oxygen levels indicate that there may be an issue with our lungs or circulation.
