After the blood gains oxygen, it goes back to the heart.  Now, the heart pumps the blood out to the rest of the body, which is waiting for the blood’s delivery of oxygen.

Next Generation Science Standards:

MS-LS1-3 Use argument supported by evidence for how the body is a system of interacting subsystems composed of groups of cells.

HS-LS1-2 Develop and use a model to illustrate the hierarchical organization of interacting systems that provide specific functions within multicellular organisms.

HS-LS1-3 Plan and conduct an investigation to provide evidence that feedback mechanisms maintain homeostasis.

Additional Information

Oxygen (O2)

Most organisms need oxygen to survive–including humans.  Therefore, without oxygen, our tissues will die in a matter of minutes.

Carbon Dioxide (CO2)

To animals, carbon dioxide is a type of waste and must be removed from the body.  However, plants can use it to conduct photosynthesis.

Lungs

They are a pair of organs, and they are responsible for respiration (breathing).
