Ok, so at the risk of sounding dumb. Atrial Naturietic Peptide comes from the atria, and Brain Naturietic peptide is from the ventricle. Well, i always assumed it was released from the the ventricles in the brain in response to increased ICP (that is why it is called Brain NP, right?) I just figured out the it comes from stretch in the heart ventricles. So my question is what does BNP have to do (if anything) with the brain?
