Question

Which organ system in humans is most directly involved in the transport of oxygen?

Answer 1

The circulatory system is most directly involved in the transportation of oxygen.

Explanation:

The red blood cells bond with oxygen allowing the oxygen molecules to be carried by the blood in the circulatory system to all the cells in the body.

If the blood becomes saturated with carbon monoxide the red blood cells can not bond with oxygen and the blood can not transport oxygen. The carbon monoxide bonds with the red blood cells instead of oxygen. The resulting death shows the importance of the circulatory system in the transportation of oxygen
