The hemoglobin which exists inside our RBCs (Red Blood Cells) carries the oxygen from lungs throughout our entire body.
By mass Oxygen
Oxygen (O2) enters your body through breathing air, which contains oxygen in it. This oxygen goes into your lungs where it is put into the bloodstream, supplied to cells in your body, returned to the lungs as carbon dioxide (CO2), and exhaled through the lungs.
Your body needs a continuous supply of oxygen due to the biochemical process of aerobic cellular respiration. During the last stage, called the electron transport chain, electrons are transferred along a series of chemicals called electron acceptors. As this occurs, energy is given off to produce molecules of ATP, the energy storage molecule of living things. Oxygen is the last electron acceptor, and once it gains the electrons it bonds with hydrogen to form water, removing the oxygen from the electron transport chain. If a new oxygen atom does not take its place immediately, the electron transport chain shuts down, and your cells will not be able to produce enough ATP to fuel their cellular processes, and they will die, and so will you. So you need a constant supply of oxygen in order to keep the electron transport chain working and producing enough energy (stored in ATP) for survival.

The heart is responsible for supply of food and oxygen to all the cells in your body. The function is done through blood supply.
25% of oxygen goes to your brain
Oxygen.
if you are burning energy faster than the body could supply the oxygen necessary for the normal reaction,. your body does that without the oxygen
oxygen and nutrients all over the body
hemoglobin
chemicals that block the supply of oxygen to the body
To supply blood with oxygen so the blood can deliver the oxygen throughout the body.
to supply more oxygen to the body
due to less oxygen supply to the body
