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.

What does your body need oxygen to make?
your body more healthier!
Why is free oxygen a problem for many organisms?
They cannot get the nitrogen they need from the atmospheric supply. WHat?
What is the oxygen demand for a human?
In Rest a normal human (65 Kgs Body Weight) will need 250ml/min. of oxygen.Depending on the activity the body might consume 15 times as much oxygen as it needs in rest.
Does blood produce oxygen?
Yes - oxygen is held in red blood cells (in haemoglobin to be precise). As the blood flows, oxygen is brought all around the body and eventually gets back to the heart and lungs as carbon dioxide (which is what you exhale).
Why do human need oxygen to survive?
Oxygen is required for cellular respiration, the production of ATP. Oxygen is an electron receptor in the Krebs cycle with reaction that transforms O2 to C02 fueling every chemical reaction (albeit indirectly) in the body.
Why do animals need a continuous supply of oxygen?
Animals need a continuous supply of oxygen because it obtains energy from their food. To acquire such energy from food, cells in animals require a steady supply of ATP in order to function. To produce this ATP, cellular respiration requires oxygen. Without ATP, cells and the organism will die so therefore, animals need a continuous supply of oxygen to survive.
What two things do neurons need a continuous supply of?
Oxygen & Glucose
What does the human body need a steady supply of?
oxygen
Does a fire have oxygen?
Yes, most fires need oxygen to burn (combustion is a rapid form of oxidation). If there is no continuous supply of oxygen, a fire will go out.
The basic funcction of respiration is to supply the body's need for?
Oxygen.
When you run you need oxygen so breathing is faster but why is heartbeat also faster?
to supply more oxygen to the body
Why does your body require a continuous amount of oxygen?
first so you wont die and the cells need to to function properly
What type of exercise depends solely on the energy that is stored in the muscle and not on oxygen intake?
This would be anaerobic exercise, where phosphates or glycosis provide the energy without the need for a continuous supply of oxygen.

Why do all human cells require a continuous supply of oxygen and removal of carbon dioxide?
They need it for mitochondria, which supplies ATP to be used as energy source.
Recent sleeping oxygen saturation level was 81 Is this normal what can cause this?
Normal oxygen saturation levels vary slightly depending on age and activity. A blood oxygen level of less than 90 percent is considered abnormal. The organs in the body need a continuous supply of oxygen to function properly. If oxygen saturation levels in the body become too low, various problems can develop. When oxygen saturation is too low it is called Hypoxemia.
