Heart failure cells are
a) Neutrophils
b) Macrophages
c) Lymphocytes
d) Basophils
Correct Answer - B
Answer- B. Macrophages
Heart failure cells are Hemosiderin laden alveolar macrophages.
Heart failure cells are a manifestation of pulmonary congestion and
edema (as seen in heart failure)
Rupture of dilated and congested capillaries may result in minute
intra-alveolar hemorrhages. The breakdown of erythrocytes liberates
haemosiderin pigment which is taken up by alveolar macrophages,
so-called heart failure cells, seen in the alveolar lumina.
