Why is the atria so thin walled?
Atria don't do nearly the same amount of work of contraction as do the ventricles. They are therefore relatively thin walled. Most of the blood that flows from the atria to the ventricles flows passively, and so the atria function mostly as a reservoir for blood volume.
