Plagiarism Medical Physiology
Hello, paragraph: "VVS originates with activation of specific areas ... and abolition of sympathetic tone." added on 11/11/2015 by 129.22.21.205 is an exact copy paste of p.579 in the book Medical Physiology by Boron and Boulpaep. I guess I could add a source but it seems like plagiarism to me. — Preceding unsigned comment added by 2A02:1810:411:A300:E09F:7952:F39D:D1DE (talk) 12:45, 14 January 2018 (UTC)

Syncope and Defecation
Does anyone know of any physiological process which would cause one the need to defecate when feeling a vasovagal syncope aura, and having symptoms subside post-defecation? Thanks. Aglassonion (talk) 10:50, 3 February 2009 (UTC)

Look up valvasa maneuver...it is due to an increased intrathoracic pressure which reduces bloodflow to the chest and decreases stroke volume/cardiac output —Preceding unsigned comment added by Johericd (talk • contribs) 21:32, 20 June 2010 (UTC)
