Answer:
The leukocytes are the main defenses of our body.
Explanation:
From the mother cell it will be a differentiation, from the mother cell to be a mother cell hematopoietic, this will turn into a lymphatic mother cell until it will be 3 different kinds of lymphocytes, the B, T and NK.
Lymphocyte B is the responsible for the inmune system based in antibodies and antigens, due to specific proteins.
Lymphocytes T, are the ones that come from the mother cell of the bone marrow. They are the responsible for the immunity against some illness like cancer.
Lymphocytes NK (natural killer) are the responsible for killing bad cells (like cancer cells) because they "eat" them in a phagocytosis process.
