The role of the atria in fluid volume control.
Neural reflexes from the heart, in particular the atria, are well documented and are involved in sodium and water excretion. Current work also indicates that the atria have an important endocrine function. Atrial peptides, which have been recently characterized and synthesized, may play a significant role in the homeostasis of body fluids.
