  • $\begingroup$ Can you provide a reference? I've never heard of it being described as a blood filter before as it doesn't carry blood. $\endgroup$ – Oliver Houston Dec 15 '17 at 11:29
  • $\begingroup$ @OliverHouston My biology teacher told me 'how does the lymphatic system filter blood?' is there any filtering that takes place in the lymphatic system? $\endgroup$ – codester Dec 15 '17 at 21:22
  • $\begingroup$ OK, I'd forgotten about the spleen being part of the lymph system... See the answer below. $\endgroup$ – Oliver Houston Dec 16 '17 at 12:35

The spleen is an integral part of the lymphatic system, and it is a major filter of blood.

The way this is done is by removing old, distorted, or antibody-coated red blood cells from circulation.

Interestingly, the spleen is enlarged with many leukemias and lymphomas.
