How can the oxygen you bring in to your body get into your circulatory system?
your lungs have structures called alveoli. The alveoli are surrounded by capillary beds which carry blood. The oxygen enters the alveoli when you inhale. The oxygen then diffuses from high concentration in your alveoli to low concentration the blood in the capillaries surrounding the alveoli.
What is the a-v O2 difference is?
The amount of oxygen taken up by the tissues in a muscle. It is the difference between oxygen concentration in the arteries and the oxygen concentration in the veins.ie. if your blood carries 20ml of oxygen per 100ml of blood and the muscle takes up 6mls of oxygen, 14mls of oxygen leaves the muscles into the veins.therefore, VO2-diff = 20ml-6ml = 14ml.
What is the fetal circulatory structure that carries blood with the lowest oxygen saturation?
Ductus arteriosus
What process does a cell with a low concentration of oxygen will likely gain oxygen molecules from an area with a higher oxygen concentration have to go through?
Diffusion.
Why do you need more nitrogen than oxygen?
Nitrogen is an inert gas it maintains a proper ratio of oxygen requred by living organisms if oxygen is in higher ratio the respiratory organs become oxidized and more oxygen in blood is harmful as low concentration of oxygen.
How is oxygen taken in into the body tissue?
At the level of the capillaries, oxygen will diffuse out of the saturated red blood cells down their concentration gradient into the tissues where their concentration is lowest.
Where is the lowest concentration of oxygen in the body?
You have low concentration of oxygen in the veins. It is low in right side of the heart. It is supposed to be the lowest before it enters the alveoli of the lungs.
Where does oxygen pass into your blood?
Oxygen diffuses into the blood in the lungs and binds to the hemoglobin since the oxygen concentration is high and the carbon dioxide concentration is low. The blood is pumped to the body. The hemoglobin releases the oxygen to the tissues because here, the concentration of oxygen is low and that of carbon dioxide is high.
Cyanosis is caused by an increased blood concentration of?
Increased concentration of oxygen
When the blood arrives at the heart it has a high concentration of what?
oxygen
What makes the concentration of oxygen low in the alveolus?
Oxygen diffuses into the blood capillary
How does ventilation help maintain a difference in oxygen concentration?
As it circulates, the oxygen diffuses into the blood via the alveolar wall, this then transfer the oxygen to the red blood cells, as diffusion occurs at this point, oxygen diffuses from a high concentration to a low concentration, so the oxygen diffuses into the blood whereas the CO2 diffuses into the alveoli and then out of the mouth when we expire.
Where is the blood with the highest oxygen concentration?
pulmonary vein or lungs
What has the highest blood oxygen concentration?
the androgerodamus vein has the most
The highest oxygen concentration is found in the blood of the?
pulmonary veins
Why our body cells have a different oxygen concentration compared to the blood flowing to them from our lungs?
Diffusion from high concentration to low concentration.The oxygen concentration in the air in the lungs is higher than in the blood.The oxygen concentration in the blood is higher than in body cells.If these differences in concentration did not exist oxygen could not move from the air to the blood to body cells. While we are alive body cells consume some of the oxygen they receive, reducing their oxygen concentration and maintaining these differences. When we die the body cells quit consuming oxygen and over a period of time the levels of oxygen slowly begin evening out (however as blood no longer moves from the lungs to the body oxygen diffusion slows dramatically, leaving some body cells with much lower oxygen levels than would be normal).
What happens to the oxygen when it reaches the blood?
As blood passes through lungs, there is exchange of oxygen and carbon bi oxide, from high concentration to low concentration and oxygen enters the blood from air to blood to make it oxygen rich.
