the backflow of blood from ventricle to atrium
escape of fluid into the pleural cavity
inflammation of the pericardium
each lobar bronchi divides into
the thick muscle layer of the heart
interference with venous return of blood to the heart due to an extensive accumulation of fluid in the pericardium (pericardial effusion)
