Watch this lecture. Note that at the 30-minute mark, the lecturer misspeaks and says that "thymus enlarges." The thymus is a small organ in the upper chest involved in the immune system. The lecturer meant to say "thyroid" when referring to a goiter in the neck. Note that the last portion of the lecture (properties of water) applies to subunit 3.1 below.
