Blood (a) body and (b) oxygen comes TO the lungs.
Blood (c) oxygen goes (d) the body.
Where does gas exchange occur?
What is A? (a)
What is B? (b)
(a) diffuses from the capillary into the alveoli.
(b) diffuses from the alveoli and into the capillary.
The (a) collects (b) from the environment and delivers it to the blood red cells simultaneously removing (c) from the blood and delivering it to the environment.
Label the image using the following choices.
Identify the larynx.
