- # 63 Summary Of Immunity
1 Phagocytes and lymphocytes are the cells of the immune system. 2 The diagram shows how to recognise phagocytes and lymphocytes in microscope slides and photomicrographs of blood. 3 Phagocytes originate in the bone marrow and are produced there throughout...
- # 62 Immunity And Vaccination
A person is immune to a disease if the pathogen that causes the disease is unable to reproduce in the body and cause illness. This happens when the body already contains, or is able rapidly to make, large quantities of antibodies against the antigens...
- # 60 Action Of B-lymphocytes
A B-lymphocyte places some of its specific receptor molecules in its cell surface membrane. If it encounters an antigen that binds with this receptor, the B-lymphocyte is activated. It divides repeatedly by mitosis to produce a clone of genetically identical plasma...
- # 58 The Immune System - Phagocytes
Credit: Pass My Exams.The human immune system is made up of the organs and tissues involved in destroying pathogens inside the body. There are 2 main groups of cells involved: ? phagocytes: ingest and digest pathogens or infected cells; ? lymphocytes: ...
- Immunity And Immune System
IMMUNE SYSTEM It is the system that gives immunity to the body by recognizing, responding and remembering foreign antigens. It plays role in allergic reaction, auto-immune disease and organ transplantation. It includes lymphoid organs, tissues, cells...

#57 Immunity - Syllabus 2015
? The immune system
? Vaccination
Candidates should be able to:
(a) [PA] recognise phagocytes and lymphocytes under the light microscope;
(b) state the origin and describe the mode of action of phagocytes (macrophages and neutrophils);
(c) describe the modes of action of B-lymphocytes and T-lymphocytes;
(d) explain the meaning of the term immune response, making reference to the terms antigen, self and non-self;
(e) explain the role of memory cells in long-term immunity;
(f) relate the molecular structure of antibodies to their functions;
(g) distinguish between active and passive, natural and artificial immunity and explain how vaccination can control disease ;
(h) discuss the reasons why vaccination programmes have eradicated smallpox but not measles,
tuberculosis (TB), malaria or cholera;
