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...

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 walls does the oxygen and nutrients diffuse?
alveoli
Where is oxygen picked up in your body?
In your lungs.
What happens in the alveoli-?
Gaseous exchange takes place in the alveoli where carbon dioxide from the bloodstream diffuses into the air.
What is the main unit of oxygen exchange in the human lung?
the capillary's, they are based on the alveoli and they pass oxygen from the alveoli sacks through to the blood stream- ready to go to the heart and be pumped around the body
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 to the oxygen when it reaches the alveoli?
oxygen enters the blood and carbon dioxide
What happens when blood passes by alveoli?
blood take oxygen from blood.
What happens when oxygen is taken in and carbon dioxide is released in alveoli?
it goes in your brain. and then eats cheese
Where in the lung does exchange of O2 and CO2 take place?
It takes place between the alveoli and the blood capillaries
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.
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.

What happens in the aveoli?
Carbon dioxide diffuses from the capillaries surrounding the alveoli into the lungs where it is exhaled, and oxygen diffuses into the capillaries surrounding the alveoli into the bloodstream where it will circulate throughout the body.
