QUESTION
Heart failure cells are?
OPTIONS
(A) Kupffer cells
(B) Intravascular cells
(C) Intra alveolar macrophages
(D) Type I pneumonocytes
ANSWER
(C) Intra alveolar macrophages
EXPLANATION
Heart failure cells are hemosiderin-laden macrophages found within alveoli, particularly in chronic left-sided congestive heart failure. They ingest erythrocytes that have escaped into alveolar spaces and accumulate iron-containing hemosiderin. Kupffer cells are hepatic macrophages, and the other listed cells are not the characteristic heart failure cells. Hence, option C is correct.
