Question

During heart surgery, red blood cells are damaged. When the blood passes through the lymphatic system, these damaged red blood cells are trapped and broken down by macrophages. In which organ in the lymphatic system does the breakdown of damaged red blood cells take place?

Answer 1

The answer is Spleen.

Step-by-step explanation:

The spleen is an organ that is part of the lymphatic system, which is located in the upper part of the left abdomen and whose main function is to facilitate the destruction of red blood cells and old or expired platelets; that is, it is responsible for the destruction of red blood cells and platelets that are old, damaged or deformed so that there is a costly renewal of circulating red blood cells. The spleen is a key place for the iron deposit and contains within it a considerable part of the platelets and macrophages available to pass into the bloodstream when necessary.

Answer 2

The answer to this question would be spleen.

The spleen is an organ that has a role in immunity, breakdown of cells and part of the lymphatic system. In this question, the red blood cells are damaged and then broken down by macrophages. The process is similar to anemia hemolytic where the red blood cells are killed by the immune cells, except it was not caused by autoimmune disease.
In both cases, the red blood cell will be broken down in the spleen. If this happens for long time, the spleen to be enlarged to increase its capacity called splenomegaly.
