Look at the following diagrams of the structure of the lung, can you use them to explain how oxygen enters the blood from the lungs and how carbon dioxide leaves the blood and enters the lungs?
- The Carbon Cycle
Carbon Cycles:Carbon can travel from the atmosphere into many place such as plants like grass. At this point in time, the carbon dioxide is either released back into the atmosphere or if the plant dies, it is put into the soil. Even after this, the carbon...

Lung Structure
Look at the following diagrams of the structure of the lung, can you use them to explain how oxygen enters the blood from the lungs and how carbon dioxide leaves the blood and enters the lungs?
Watch this video clip below and then explain carefully how oxygen and carbon dioxide are exchanged at the alveoli.
