Most lymphocytes are actually not circulating contained by the blood but are sequestered in lymphoid tissues, such as lymph nodes and the spleen. The ones that circulate contained by the blood are exposed to antigens, and they report back to others and put into action the immune system. When they're turned on, the proliferate like crazy! (This is why you grasp swollen lymph nodes sometimes when you have an infection.)
Also, one lymphocyte can pump out thousands and thousands of antibodies (plasma cell do this), and the antibodies bind to antigens so that other cells endorse, ingest, and kill it. So it really doesn't pinch too many cell to fight sour an infection b/c our immune system is pretty efficient.
There's like mad more detail involved, but that's the main gyst of it. If you're interested surrounded by learning more, bear an immunology course or read up on the topic. It's really interesting, and it's amazing how all the different cell types interact to m¨ol¨|e off the desperate stuff! :)
Hope this helped!
Actually it isn't such a small number, it merely looks small compared to RBC's. Two other things
1. They concentrate where an antigen attack is localized.
2. There are plenty of them, in fact precursors, in the lymphatic system waiting for march orders, so to speak.
