How the left ventricle failure cause pulmonary edema .. and congestive heart failure ( right ventricle failure) cause cardiac edema .. ?
In left ventricular dysfunction there is increased back pressure in the pulmonary veins because the ventricle is not able to pump the blood to the body which in turn increase the pressure in the left atrium because there is no more space for blood to go in the left ventricle.... this increase in pressure in the pulmonary veins causes pulmonary venous congestion resulting in pulmonary edema. However in rt heart failure there is increased congestion in dependent veins of the body like that of legs causing cardiac edema. I hope I helped you to a better understanding!
left ventricle cant pump to the rest of the body thats why the blood backflow to the lungs
if blood cant be ejected naturally it will backflow back to pulmonary vein causing edema
In left ventricular dysfunction there is increased back pressure in the pulmonary veins opening in the left atrium which cause pulmonary venous congestion which in turn causes pulmonary edema. However in right ventricular dysfunction the venous return from the body is decreased which causes congestion in the dependent vein of the body like those of the legs, hence causes cardiac edema
