oxygen binds with hemoglobin in the lungs and forms oxyhemoglobin.
Hemoglobin is the compound in red blood cells that carries oxygen from the lungs to body cells. The oxygen combines readily with the ion in hemoglobin, and hemoglobin can carry more than twenty times its own volume in oxygen. After releasing oxygen to the cells, hemoglobin collects carbon dioxide and carries it to the lungs where it is exhaled.
oxygen makes your blood red. The Lungs put lungs into your blood system.
Transports oxygen from the lungs to the body tissues. Hemoglobin is what gives red blood cells their color.
I believe it might be HEMOGLOBIN.
It attaches itself to red blood cells(erythrocytes). Hemoglobin is what transports oxygen from the lungs to the rest of the body.
The molecule that gets picked up at the lungs and dropped off at body cells is oxygen. Oxygen is transported by red blood cells in the bloodstream, binding to hemoglobin for delivery to various tissues and cells in the body.

Basically hemoglobin is intended for oxygen transport from lungs to brain, muscle and whole body as needed...
The same hemoglobin molecules that absorb oxygen in the lungs release it to the cells in the capillaries and pick up carbon dioxide from the cells. When the blood returns to the lungs, the hemoglobin releases the carbon dioxide and replaces it with fresh oxygen. The carbon dioxide released by the hemoglobin travels across the membranes in the lungs and is breathe out when we exhale.
The part of the blood that is responsible for carrying oxygen is hemoglobin. The hemoglobin binds to oxygen in the alveoli of the lungs. Then the hemoglobin releases the oxygen at the cells. The part of the hemoglobin molecule that is directly responsible for carrying the oxygen is the iron ion in the center of the molecule's structure. The iron ion changes from a Fe +2 ion to a Fe +3 when carrying the oxygen. Then the hemoglobin reaches the cell, the iron ion decomposes back to the more stable Fe +2 state, replacing the oxygen with a water molecule.
