yep :)
it is 65% oxygen
Oxygen circulates through the body in blood. A molecule of oxygen (O2) from the lungs binds loosely to a molecule of hemoglobin in a red blood cell. The red blood cell travels through the capillaries and the oxygen molecule is released from the hemoglobin and is delivered to the cells.
The molecule that bind oxygen in the blood stream is hemoglobin. The O2 attaches to the molecule allowing it to be carried around the body to the other cells.

I depends. There are two separate answers. In the lungs the final destination is the alveoli. This is where the gas exchange takes places to allow oxygen rich blood into the bloodstream and take out the carbon dioxide. In the body once the blood is oxygen rich in the bloodstream it travels through ateries and eventually to capillary beds where gas exchange takes place. The oxygen depleted blood travels back to the alveoli in the lungs and out into the atmosphere.
Oxygen and Hydrogen
Oxygen and Hydrogen
Oxygen molecule, generally it is O2 and is what we breath in. As in Oxygen goes into our body to carry out aerobic respiration.
Red Blood Cells carry oxygen to other body cells by using a molecule called hemoglobin. This molecule contains iron which is what oxygen is actually attached to.
You must have oxygen delivered to every cell in your body at all times. If you don't, all processes that require oxygen will stop. You use glucose to make ATP (an energy carrying molecule) but it requires oxygen as the final electron acceptor. If oxygen isn't there, all will stop. Cyanide has the ability to stop this reaction and your body will stop in about 2 minutes.
Hemoglobin is the molecule that carries oxygen, so it can be thought of as the 'root' or base that allows it to do its job.
