my guess is facilitated transport so since anyone could write anything on here weather is wrong or not. i decided to show ya.
CORRECT ANSWER IS:Diffusion
facilitated transport is wrong

What gas leaves the blood in pulmonary capillaries and enters the alveoli?
carbon dioxide
What is the site at which oxygen enters the pulmonary blood?
Oxygen enters the pulmonary blood in the capillaries of the alveoli -- the air sacs of the lungs.
Why do blood capillaries surround alveoli?
The alveoli are the sites of respiration: the oxygen in them provided by the inhaled air diffuses into the blood cells that flow through the capillaries. Carbon dioxide diffuses out of the blood and into the alveoli so it can be exhaled. The capillaries provide a way for the blood to reach the alveoli. Hope this helps
O2 enters the capillaries and ----- from the capillaries passes in to the lungs?
Carbon dioxide is produced as a waste product of respiration, and is taken in the bloodstream to the capillaries outside the lungs, where the CO2 diffuses into the alveoli of the lungs.
Where in the human body is o2 and co2 exchanged?
Human gas-exchange occurs in the lungs. Once air enters the lungs, diffusion of O2 and CO2 occurs in the alveoli.
What allows oxygen in and waste out?
As oxygen enters the body it will travel down the trachea (throat), through the bronchioles (tubes leading to the lungs), and into the lungs. In the lungs there are very tiny grape-like-sacs called alveoli. The membrane on these sacks is very thin, and they are surrounded by many tiny capillaries (blood vessels) whose membrane is also very thin. It is here where oxygen from the alveoli enters the capillaries, and carbon dioxide (waste product) from the capillaries enters the alveoli. The oxygen is now carried through the blood to the heart where it is pumped throughout the body, and the carbon dioxide, now in the alveoli, is expelled as the person exhales. In a situation of altitude it is this process that is hindered. Because of the lower pressure of oxygen the oxygen does not enter the capillaries as easily and the body is deprived of oxygen.
Are capillaries part of the lung?
Yes, capillaries form a network around the alveoli. It is through the alveolar walls and into the capillaries that oxygen enters the blood stream. Carbon dioxide leaves the blood by the reverse route.
How can the oxygen you bring in to your body get into 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.

At the end opf the bronchioles are small air sacs called what which is where the oxygen enters the blood through the capillaries?
They are called alveoli
What is a function of a respiratory system?
Human respiration, as a person takes a breath in the air rushes into the lungs causing the alveoli to expand. The alveoli are like little balloons with air on the inside and tinny blood vessels, called capillaries, surrounding the outside. The lungs expand as the alveoli fill up with air. The concentration of oxygen in the air of the alveoli is higher than the concentration of oxygen in the blood inside the capillaries, which results in oxygen diffusing from the alveoli into the capillaries. At the same time the carbon dioxide level in the capillaries is high and low in the lungs. So carbon dioxide also diffuses, but in the opposite direction! (carbon dioxide leaves the capillaries and goes into the alveoli) When a person exhales the lungs decrease in size as the air rushes out. Quick over view, breathe in: Oxygen from the alveoli diffuses (enters) into the capillaries Carbon dioxide from the capillaries diffuses (enters) into the alveoli to be exhaled out. (note: water vapor is also exhaled out with the carbon dioxide, that is what you see on a cold winter day when you exhale) or CO2 (carbon dioxide) + H2O (water) vapor out O2 (oxygen) in
