a) Make a front view drawing of the inside of an alveoli (in the space below) with a blood vessel
surrounding it on the outside.
b) Label the alveolus and the blood vessel.

carbon dioxide is high (↑) or low (↓).
f) Label the direction of blood flow with an arrow.
g) Show the direction of movement of oxygen (into the blood vessel or into the alveoli) by drawing an
arrow in the appropriate direction. Make sure to write the name of the gas.
h) Show the direction of movement of carbon dioxide (into the blood vessel or into the alveoli) by drawing
an arrow in the appropriate direction. Make sure to write the name of the gas.
