It basically is used to burn fuel to power the body, more or less just like a campfire uses the air to burn. When the blood goes to the lungs, oxygen is absorbed in and as it leaves the lungs to go to the different parts of the body, it provides the energy. Therefore, the lesser the amount of oxygen in the blood, the weaker we become and body organs will die ultimately.

∙ 14y agoWhen you breathe in, oxygen travels down your throat and into the bronchi. After that, the air goes into each lung. The air goes down into the bronchioles until it reaches the alveoli. Once the air is in the alveoli, the oxygen passes into the pulmonary capillary. And the oxygen gets into the bloodstream. The oxygen goes to the brain to keep it healthy functioning.

The blood cells return the oxygen (now carbon dioxide) to your lungs to be exhaled before returning to your heart. Which takes all of 2 seconds.

Before it is exhaled, some of the oxygen is absorbed through the membrane wall tissue, and into the bloodstream.

Do you exhale to remove excess oxygen from the lungs?
No- exhaling removes carbon dioxide from your lungs- along with nitrogen that you had inhaled, and any oxygen that was not transferred to red blood cells.
How does oxygen from the air get into the blood?
oxygen that is inhaled into the lungs is diffused through the small air sacs, called alveoli, into the bloodstream.
Inhaled oxygen diffuses through the walls of what?
Inhaled oxygen will diffuse through the walls of the lungs. It will also diffuse through the walls of red blood cells so it can be carried all over the body.
What substance needed by the body cells enters the body through the lungs?
O2 and Co2, but we breathe out the Co2 again + the O2 which is converted in more Co2
What duty do the lungs perform?
They allow gaseous exchange between the inhaled oxygen and the exhaled carbon dioxide.
How is inhaled air different from exhaled air?
Because the body has used the oxygen in the air to oxidize the nutrients you eat, this process combines the oxygen that you inhaled with carbon which makes up part of the nutrients you eat to form a poisonous gas "carbon-dioxide" which is then transported back to the lungs and exhaled along with moisture.
Why are slow breaths are more effective then short quick breaths?
Your body only uses 1/4 of oxygen inhaled. Longer in your lungs means more oxygen used, less energy consumed.
What oxygenates the blood?
The red blood cells pick up oxygen from the air that is inhaled into the lungs. When the red cells pick up the oxygen from the air, they expel carbon dioxide into the lungs to be exhaled.
Where is the site for gaseous exchange?
The site for gaseous exchange is the lungs. Carbon dioxide is exhaled and is substituted for oxygen which is inhaled.
Why is the lung important to the body?
Without the lungs, you're wasting your breath. They introduce the inhaled oxygen to your circulatory system.
What is breathed out?
Air is breathed out of the lungs in the form of carbon dioxide. Air that is inhaled is called oxygen.
Where does oxygen go after being inhaled by mouth?
Oxygen after inhalation is absorbed by hemoglobin of blood in the lungs and from there it is distributed in the entire body through blood streams.
