Summary• Oxygen is necessary for life
• Oxygen in the air is taken into the body through your lungs when you breathe in
• Oxygen goes from the lungs into the blood and is carried to the cells throughout the body
• Cells use oxygen to make energy from food
• Waste (carbon dioxide) from the cells is carried back to the lungs by the blood
• Carbon dioxide leaves the body when you breathe out
