The oxygen diffuses into the bloodplasma in the capillaries in the lung, from there it diffuses into the erythrocytes (red blood cells, RBC's) and from there it gets bound to Hemoglobin (haemoglobin).
The diffusion of oxygen can take place because the oxygenconcentration in the bloodplasma is very low (and the same goes vor the erythrocytes). Because of the diffusion eventually the concentration in the air in the alveoli, the bloodplasma and the erythrocytes would become equal and the diffusion would stop. This is where the hemoglobin comes into play, by binding oxygen hemoglobin lowers the concentration of oxygen in the erythrocyte, because of this oxygen from the bloodplasma will diffuse into the erythrocyte thus lowering the concentration in the plasma thus causing more oxygen from the alveoli to diffuse into the bloodplasma. This cycle goes on until the haemoglobin in the erythrocytes if fully saturated, or the blood leaves the lungcapillaries.
Note: bloodplasma, h(a)emoglobin and maybe some other words might not be spelled correctly (but I'm sure they'll sound familliar and you'll know the correct spelling), I'm sorry...
What else can I help you with?
How do alveolar and capillaries work together to provide the muscles with oxygen?
as it moves through blood vessels capillaries in the alveoli walls, your blood takes oxygen from the alveoli and gives off carbon dioxide to the alveoli
What part of the respiratory system does blood get oxygen from?
Blood gets oxygen from the air in the alveoli of the lungs, where oxygen diffuses across the thin walls of the alveoli and into the surrounding capillaries. This process is known as gas exchange.
What happens in the alveoli-?
Gaseous exchange takes place in the alveoli where carbon dioxide from the bloodstream diffuses into the air.
Is gas exchanged in the pleura?
Gas exchange does not occur in the pleura. The pleura is a membrane that lines the outside of the lungs and inside of the chest cavity. Gas exchange, where oxygen is taken in and carbon dioxide is removed, happens in the alveoli of the lungs.
How does respiratory system take in oxygen and release carbon dioxide?
In the alveoli
Describe what happens in the alveoli sacs?
When we inhale in and out oxygen moves from the alveoli to blood carbon dioxide moves from blood to alveoli.
What happens when blood passes by alveoli?
blood take oxygen from blood.
What happens to the oxygen when it reaches the alveoli?
When oxygen reaches the alveoli in the lungs, it diffuses from the air in the alveoli into the surrounding capillaries. The oxygen then binds to hemoglobin in red blood cells, which transports it to the body's tissues for use in cellular respiration.
What happens when oxygen is taken in and carbon dioxide is released in alveoli?
it goes in your brain. and then eats cheese
What gas enters the alveoli?
Oxygen is removed from the alveoli by the cappillaries.
What system allows for the exchange of carbon dioxide and oxygen between the air and the blood?
It happens in the alveoli of the lungs
Oxygen diffuse into the blood at the alveoli?
Carbon dioxide does.
Why oxygen diffuses from the alveoli into the blood?
Oxygen diffuses from the alveoli into the blood because of a concentration gradient. The partial pressure of oxygen in the alveoli is higher than in the blood, so oxygen moves across the thin membrane of the alveoli into the blood to reach equilibrium.
Where in the lung does exchange of O2 and CO2 take place?
Gas exchange between oxygen and carbon dioxide takes place in small sacs called alveoli, which are located at the end of the respiratory bronchioles in the lungs. This is where oxygen from the air is transferred into the bloodstream and carbon dioxide is removed from the blood.
What are the alveoli and what happens in them?
the alveoli is happen the blood
What happens to blood when it leave the alveoli?
It is returned back to the heart to be sent throughout the body to deliver nutrients such as oxygen.
How can the oxygen you bring into your body get to 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.
