A decrease in blood pressure at the arterial baroreceptors would result in which of the following? increase in heart contractility (sympathetic nervous system activity would be increased because of the low blood pressure. Sympathetic fibers go to the ventricles of the heart and increase their contractility. An increase in contractility would increase stroke volume which would lead to an increase in cardiac output and blood pressure.) A decrease in fluid osmolarity may result from ingest...
