Final answer:
Red blood cells enable oxygen to move from the lungs to cells throughout the body.
Step-by-step explanation:
The component of blood that allows oxygen from the air to move from the lungs to cells of the body is red blood cells. Red blood cells contain a protein called hemoglobin that binds with oxygen in the lungs and transports it to the cells throughout the body. Hemoglobin carries oxygen and releases it where it is needed, enabling cells to carry out their functions.
