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?

The right answer is The spleen.

The spleen belongs to the lymphatic system, its role and to filter the blood and purify it. It works mainly on the destruction and recycling of spent red blood cells (iron is used again for example for the production of hemoglobin).

Like the liver, the spleen also serves as a store of blood for the body.
