Answer the following questions:1. How does blood help in the transport of oxygen?

Answer»

EXPLANATION:

All red blood cells CONTAIN a red pigment known as HEMOGLOBIN. Oxygen binds to hemoglobin, and is transported AROUND the body in that way. In tiny blood vessels in the LUNG, the red blood cells pick up oxygen from inhaled (breathed in) air and carry it through the bloodstream to all parts of the body.
