Question: @ triona how does the other lymphocyte cells in our body remove the dying one

Tríona O'Connell answered on 17 Nov 2014:

Lymphocytes don’t remove cells themselves. They label them for removal (think pointing out that the bin needs to be put out, but not doing it yourself). Other cells of the immune system called macrophages (big eaters is what their name means) literally gobble up the bits of dead cells and recycle what they can.
