<P> Wandering Cells are probably amoeboid when alive but after fixations they are seen to possess a distinct nucleus . These cells are regarded as a special type of blood cell . The cells were found to take up iron saccharate, which had been injected into the haemocoele . The cell's cytoplasm contains a variety of inclusions and characteristically, a well - markedeosinophile area . The wandering cells of nudibranchs are excretory taking up effete matter from the harmocoele and discharging it into the lumen of the gut . </P> <P> Lymphocytes are just one group of cells that function as part of the immune system . More of this group travel around the lymphatic system than in the blood network . Two types of lymphocytes are present in the bloodstream, which are the B cells and the T cells . </P> <P> B cells are wandering cells that are antibody factories . They are capable of producing molecules that can recognize and bond to specific types of molecules present in infectious organisms or substances that the body identifies as foreign . Every individual B cell makes only one particular type of antibody, specific to only one type of foreign substance . For example, where one cell produces antibody against one of the many viral causes of a cold, another cell's antibodies will ignore the presence of the same virus completely . Normally, the body contains many different B cells, specialized for a specific invader, but only has low levels of each type circulating . When an invader manages to break past other defenses, like the skin or digestive tract into the body, then the circulating B cells that target that particular foreigner multiply up and produce more antibody . Special forms of B cell called plasma cells produce antibodies; little versions of the specialized B cells, called memory B cells, remain stored in lymph glands prepared for the next invasion by the foreigner . Although the products of B cells, the antibodies, stick onto their target invader, they most often do not kill the invader . This job falls to other types of lymphocytes called T cells . There are three different forms of T cells, which are the Helper T cells, the Killer T cells, and the Suppressor T cells . </P>

Which is an example of a wandering cell
