Breathing
Define:
Medulla oblongata

Know how breathing is regulated. What molecule is responsible for breathing rate and depth within humans.
Know Figures 9.14 & 9.15
Know how Oxygen and Carbon Dioxide are carried within the blood. The enzyme: Carbonic Anhydrase is
present in large amounts in RBCs. What reaction do you think Carbonic Anhydrase regulates within the
body? (HINT: is in your textbook and is a reversible reaction – that is it occurs in both directions – in the
body tissues and in the lungs).
