[CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
|
|
|
the right atrium and ventricle pump against lower pressures, resulting in the systemic pooling of venous blood.
|
|
|
diffusely collapsed alveoli cause blood from the right side of the heart to bypass the alveoli and return to the left side of the heart.
|
|
|
increased pressure in the left atrium and pulmonary veins forces serum out of the pulmonary capillaries and into the alveoli.
|
|
|
an acute myocardial infarction or chronic hypertension causes the left ventricle to pump against decreased afterload, resulting in hypoperfusion.

Detailed explanation-1: -Cardiogenic pulmonary edema is caused by increased pressures in the heart. It’s usually a result of heart failure. When a diseased or overworked left lower heart chamber (left ventricle) can’t pump out enough of the blood it gets from the lungs, pressures in the heart go up.
Detailed explanation-2: -Left-sided heart failure is related to pulmonary congestion. The left side of the heart receives oxygen-rich blood from the lungs. When the left side is not pumping correctly, blood backs up in the blood vessels of the lungs-pulmonary edema.
Detailed explanation-3: -The four physiologic categories of edema include hydrostatic pressure edema, permeability edema with and without diffuse alveolar damage (DAD), and mixed edema where there is both an increase in hydrostatic pressure and membrane permeability.
Detailed explanation-4: -Mitral valve regurgitation is understood to cause pulmonary edema as a result of increased intravascular hydrostatic pressure.
