Oxygen diffuses from any place there is a lot of it to any place where there is less. In the body, it diffuses from the air in the alveoli of the lungs, through the lung and capillary walls and into the blood, where it is taken up by the haemoglobin of the red blood cells. When the bood reaches the body tissues it diffuses out of the blood and into the cells.
Oxygen is inhaled through the mouth and nose, travels through the trachea and bronchi and into the lungs. From there it goes into the alveoli and diffuses through the capillaries. It attaches to haemoglobin in the blood.
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.
the lungs!!
A semipermeable membrane.
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.
o2 diffuses into blood from alveoli of lungs through the respiratory membran.
When there is more oxygen in an alveolus than in the blood around it oxygen diffuses from the capillaries to the veins. This is due to the high concentration of oxygen in the alveoli.

oxygen
Carbon dioxide does.
Oxygen diffuses into the blood capillary
your lungs
Oxygen diffuses from the alveoli of the lungs into the blood. Carbon dioxide diffuses from the blood into the alveoli of the lung where is will be exhaled.
It diffuses into the blood capillaries surrounding the alveoli.
the answer to apex is passive.
Internal respiration
