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.
macrophages
recognizes all antigens ( anything that induces a specific and adaptive immune response)
Yes, it is. Microbes can get in through any hole in your body, and your ear holes are one of them. The ear wax is a sticky substance that stops microbes from infecting your ears and letting your body get infected by microbes. Further answer I personally don't see it as part of the immune system. Defence system - yes, immune - no. The immune system fights bacteria and other foreign bodies by developing anti-bodies which kill them, generally in the blood stream. Not quite the same thing as stopping stuff getting into your ear in the first place.
Helper T cells
An adaptive immune system is a series of specialized, systemic cells and processes which remove or counter pathogenic growth.
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.
tissues
T helper cells
Your immune system.
Antigens
They're abnormal immune responses - by definition, an allergy is an inappropriate response to a foreign substance. After all, it's not known as an 'allergy' when people's immune systems attack harmful pathogens, despite the body mounting somewhat similar immune responses.
Also. Allied the innate immune system, cells and proteins involved recognize structures shared by classes of microbes not present on the body's own cells and can also recognize molecules released by infected, damaged, or dead cells. The innate system can eliminate microbes on its own but more commonly cells of the innate immune system release chemokines to attract cells that are involved in the adaptive immune system to initiate an antigen or microbe specific immune response
Lymphocytes(T and B cells)
Humoral
The adaptive immune system is activated if the innate immune system is unable to control the infection.
