It's not really the blood that needs the oxygen. All the living tissues in our bodies needs a steady supply of oxygen, and the blood is what carries that oxygen around and delivers it where it needs to go.

Why do blood cells need oxygen?
Blood cells need oxygen to move and reproduce, without it, they would die. And in time, you would also die.
What happens when blood reaches tissue that doesnt have enough oxygen?
Once oxygenated blood reaches the capillaries, the velocity of the blood is very slow - which favours the exchange of oxygen. Oxygen therefore diffuses across the walls of the capillaries into the tissues that need it.
Why do you breathe slower when you are at rest or sleep?
Because you don't need to get as much oxygen to your blood for respiriation as you do not need more energy. When you are exercising you breathe faster to get that extra oxygen.
What is responsible for picking up the oxygen in lungs and carrying it to all the body cell that need it?
The red blood cells in the blood are responsible for picking up the oxygen in the lungs.
Why does the brain need so much oxygen?
Your cells need the oxygen to function. That's why it's called "cellular respiration."and you blood needs to be oxygenated so it can carry the O2 (oxygen) to other parts of the body.
Why is oxygen needed in blood?
Because your cells need oxygen. Blood has Hemoglobins inside it, which carry oxygen.
Why is it important for your heart to separate oxygen rich blood from oxygen poor blood?
If the oxygen-rich blood and the oxygen poor blood mix the amount of oxygen becomes diluted. The cells and tissues need more oxygen than they will get.
Why is it important for your heart to keep oxygen-rich blood separate from oxygen poor blood?
If the oxygen-rich blood and the oxygen poor blood mix the amount of oxygen becomes diluted. The cells and tissues need more oxygen than they will get.
Why is it important for your heart to keep oxygen rich blood separate from oxygen-poor blood?
If the oxygen-rich blood and the oxygen poor blood mix the amount of oxygen becomes diluted. The cells and tissues need more oxygen than they will get.
Where is oxygen in the human body?
oxygen if everywhere. In the heart, lungs, blood. YOu need blood everywhere to live!
Does the body need oxygen because it needs to make more blood?
No, your blood would stop running if you get no oxygen, but at the same time you would need oxygen to keep your blood going. So its a good chance of 'no'
What do white blood cells need?
oxygen,
Why does the oxygen need to travel into the blood?
All the cells require oxygen, and so the way of them getting it is via the blood.
Do you need oxygen to aerate the lungs and to cleanse the blood?
No, you need AIR (which contains 20% Oxygen) to areat the BLOOD in the lungs and to carry away CO2. No, you need Kidneys to cleanse the blood.
Why do blood cells need oxygen?
Blood cells need oxygen to move and reproduce, without it, they would die. And in time, you would also die.
When will oxygen diffused in to the cell?
Oxygen is diffused into the cells when the cells need oxygen to carry out their functions. Oxygen is carried inside a red blood cell where the oxygen is bound to the hemoglobin. Red blood cells travel in the blood as part of the circulatory system and diffuse or give oxygen to the cells which need them. Oxygen is important for many cellular functions.
Which chemical reduces oxygen in the blood causing a difference between the amount of oxygen the cells need and the amount of oxygen the blood can supply?
carbon monoxide.
