The respiratory system seems like the obvious answer, but you used the word absorb. The respiratory system takes air into the lungs, but the red blood cells (erythrocytes) absorb the oxygen out of the air taken into the lungs. The circulatory system then delivers these red blood cells to the capillaries where the oxygen is traded for carbon dioxide as the cells need.
Inside the alveoli, oxygen moves across paper-thin walls to the capillaries (tiny blood vessels) and into the blood. It is then picked up by chemicals (haemoglobin) in the red blood cells that carry it around the body. At the same time, waste products from the body, in the form of carbon dioxide, come out of the capillaries back into the alveoli, ready to be breathed out. Freshly oxygenated blood is carried from the lungs to the left side of the heart which pumps blood around the body through the arteries. Once the oxygen has been used up, the blood returns, through the veins, to the right side of the heart. From there it is pumped to the lungs so that the carbon dioxide can be removed and more oxygen taken on board.
Just dab it on the wound with a cotton ball or you can pour it. The catalase enzyme in our body will react with the Hydrogen peroxide releasing the extra oxygen molecule in the H2O2. Bacteria cannot survive in this very rich oxygen environment so they die instantly.
No, Norvasc (amlodipine) does not contain nitrates. It is a calcium channel blocker used to treat high blood pressure and angina, while nitrates are a different class of medications used to treat angina and heart conditions.
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).
Oxygen
It is the heart that pumps fresh oxygen in the blood.
The main energy supply to the heart is oxygen supplied by the coronary arteries. For more information contactHeartquestionsanswerd@hotmail.co.uk To get ANY heart question answerd. Use this information as a guide only I am NOT a doctor but I know a lot about the heart.
the heart does not give the body it's oxygen it is the lungs. The heart is used to pump the blood to the lungs to pick up oxygen and then to pump the blood throughout the body and add oxygen to the blood cells.
oxygen is taken in and CO2 is released.
oxygen is taken in and CO2 is released.
The amount varies widely, depending upon factors such as the size of the individual and intensity of physical activity (for two).
We used more oxygen .
Oxygen was the first element used by humans the most prominent elements in the body are hydrogen OXYGEN nitrogen and carbon. You have probably heard that you body is made up of 65 percent water well you are also made up of 65 percent oxygen. I know that does not equal 100 percent but water is H2O which is hydrogen squared and Oxygen. Oxygen is in water. We need oxygen to live.
The heart sends "used" blood to your lungs so that the blood can reabsorb oxygen there. There are no weasels in the lungs.
Oxygen is taken in and glucose is used. Water, Carbon dioxide and energ are created.
Oxygen is taken in by cellular respiration.
