The adaptive immune system was developed in higher vertebrates to combat pathogens and antigens. These can include viruses, bacteria, and anything else that can cause the immune system to launch an immune response.
Lymphocytes(T and B cells)
They are called as immunoglobulins.
recognizes all antigens ( anything that induces a specific and adaptive immune response)
Helper T cells
adaptive immune response
An adaptive immune system is a series of specialized, systemic cells and processes which remove or counter pathogenic growth.
Innate and adaptive.
Acquired Immune System or Adaptive immune System
T helper cells
Generally, they don't engage in cell to cell combat; they are the building blocks of life. However, microbes and invaders do attempt to take over more advanced organisms. That is why there is an immune system. One type of immune cells are the phagocytes, and they surround invaders and "eat" them as their name implies.
