Oxygenated blood is carried through the body by arteries. There is one exception though - the pulmonary artery carries de-oxygenated blood to the lungs; the pulmonary vein returns to the heart carrying oxygenated blood.

The blood oxygen bound to hemoglobin is called oxyhemoglobin. This is the form of hemoglobin that carries oxygen from the lungs to tissues throughout the body.
Oxygen is attached to the haemoglobin in the blood and a small portion is also dissolved in the plasma of the blood
Red blood cells. Oxygen reacts with haemoglobin in red blood cells to form oxyhaemoglobin, which is what gives the cell its colour.
I remember learning that the oxygen attaches itself to something in our blood cells called hemoglobin's.
Oxygen is transported as reduced hemoglobin in the blood. In this form, hemoglobin has bound to oxygen molecules and is carrying them to tissues throughout the body.
Hemoglobin is an iron-containing protein. Hemoglobin contains a hemo prosthetic group that has an iron atom at its center. When the iron is bound to oxygen, the hemo group is red in color (oxyhemogoblin), and when it lacks oxygen (deoxygenated form) it is blue-red.

Iron is the mineral that enables red blood cells to carry oxygen. It is a key component of hemoglobin, the protein in red blood cells that binds to oxygen and transports it throughout the body.
The red blood cells in the blood carry oxygen to the cells. The oxygen is bound to hemoglobin, a protein in the red blood cells, and is transported throughout the body via the circulatory system.
