The pathway of O2 from alveoli to blood vessel
The oxygen molecules move from high pressure to low pressure. The partial pressure of oxygen is more in the alveoli as compared to blood vessels
The alveoli and the blood vessel and their basement membrane all these are connected together and that is the spot where the transfer occur
The oxygen molecules come near the alveoli and pass across the basement membrane and reaches the blood vessel . The oxygen move to the blood vessel because the partial pressure of O2 in alveoli is more than that in blood vessel . This oxygen molecules that reach the blood vessel then gets attach with the hemoglobin molecules and move to different parts of body .

The small capillaries in the lungs are in close contact with the alveoli. A red blood cell takes up oxygen during the 0.5 s that it squeezes through a capillary at the surface of an alveolus. What is the diffusion time for oxygen across the 1-μm -thick membrane separating air from blood? Assume that the diffusion coefficient for oxygen in tissue is 2×10−11m2/s. Give your answer to 1 significant figure.

During respiratory exchange, carbon dioxide moves from the blood into the alveoli due to: the presence of a permease , which removes carbon dioxide from the capillaries. the contraction of the diaphragm, which creates a vacuum that pulls it out. diffusion down a concentration gradient. the air pressure of dissolved oxygen, which forces it out. two of the choices are correct

You are a molecule of oxygen floating happily through the atmosphere when all of a sudden you are inhaled by Ms Magenta. Trace your pathway through Ms Magenta respiratory tract beginning in her nasal cavity to the point at which you cross the respiratory membrane and enter the pulmonary capillaries.
