UNIT 11-IMMUNITY🤎 Flashcards
what is an external and internal defence system? (for understanding, not in syllabus)
💚
give two types of white blood cells, state the difference between self antigens and non-self antigens
💚
why does the immune system recognise pathogens?(2) explain what an antigen is
💚
explain what cell surface antigens are (2)
not on syllabus, just for understanding
💚
how are anti-bodies made? (1)
😕
explain why people with blood group A cannot receive blood from people with blood group B (not on syllabus, just for understanding)
💚
name two kinds of cells of the immune system, draw and name types of those cells, how and where are these cells produced?
💚
state the use of phagocytes, talk about the differences between the two types of phagocytes (6)
😕
explain the process of phagocytosis in detail, use diagrams if necessary, add all keywords
😕
give three characteristics of lymphocytes
😕
explain the difference between B cells and T cells in detail (in terms of their location(2) and role in the body)
😕
explain the orgin and maturation of b cells in detail using key words and diagrams if necessary
😕 STOPPED HERE
explain what happens with b cells during an immune response in detail and with diagrams (include the difference between the two types of b cells in this explanation)
❤️During an immune response, B cells carry out an immune response by dividing by mitosis to form a variety of cells, each type of cell is specialised to respond to one type of antigen. B cells can divide to form memory cells or plasma cells
explain the difference between a primary and secondary immune response with the use of a graph, describe the sequence of events of a primary immune response with reference to macrophages, b lymphocytes and T lymphocytes,
❤️
explain the molecular structure of anti-bodies in detail and how this helps them carry out their function
❤️
