diffusion - the natural movement of particles from high to low density. oxygen dissolves in a film of liquid water lining the alveoli (tiny air sacs in the lungs) and the wall of the alveoli and wall of the capillary (each 1 cell thick) into the blood in the capillary. the oxygen is moving from the high concentration of oxygen in the lung to the low concentration of oxygen in the blood. this low concentration is maintained in the blood since it continuously flows away and is replaced by oxygen poor blood. the high concentration of oxygen in the lungs is of course maintained by breathing in fresh air.
Diffusion.
Oxygen diffuses from a high concentration in the alveoli to the oxygen concentration of the pulmonary capillaries.
Oxygen moves from the lung into the bloodstream at the capillaries of the alveoli. This happens due to diffusion.

Oxygen is moving by simple diffusion. It is going from a higher level of oxygen (air) to lower (blood).
deoxygenated blood
Oxygen moves into the lungs to the alveoli in the lungs into capillaries into pulmonary veins to the heart then to arteries that go through the rest of the body.
A protein called hemoglobin present in red blood cells is able to bind oxygen molecules. Capillaries surround the alveolar sacs in the lungs where oxygen diffuses into the blood where it is bound by hemoglobin. Now, the oxygen is in the blood.
Inside the red blood cells, the iron has a great affinity for oxygen. It moves by passive diffusion from the alveoli in the lungs into the bloodstream where it binds to the iron groups in the haemoglobin in the red blood cells.
Yes. This what happens. The oxygenated blood goes to the heart and is pumped out via arteries and end up in the capillaries where the oxygen is exchanged with carbon dioxide and it moves into the body cells.
breathing
i don"t know is call sorry find it your selfs
respiratory system
the oxygen releases carbon dioxide
