Immune System

QuestionAnswer
Name the 3 types of non specific defences 1. physical barriers 2. chemical secretions 3. inflammatory response
Describe a physical barrier Closely packed epithelial cells in respiratory/digestive system.
State two examples of chemical secretions 1. tears 2. salvia 3. mucus 4. hydrochloric acid
State the name of the white blood cells that release histamine in the inflammatory response mast cells
Explain why blood flow increases after histamine release vasodilation of arterioles OR increased capillary permeability
Explain the importance of increased blood flow to an area of inflammation/infection phagocytes AND clotting factors brought to area
Describe the process of phagocytosis Phagocyte engulfs pathogen and digestive enzymes destroy pathogen
Explain how phagocytes accumulate at the site of infection phagocytes release cytokines to cause more phagocytes to accumulate
State the type of white blood cell in the specific immune system Lymphocytes
Which type of lymphocyte does apoptosis T lymphocytes
Define apoptosis Programmed cell death
Describe what happens after a specific T lymphocyte binds to a specific pathogen protein diffuses into infected cell
Describe the impact of protein being released into the cell during apoptosis Activates self destructive enzymes which calls self death
Describe what is meant by autoimmune disease When T lymphocytes react to self antigens destroying the body's own cells.
Describe the impact of HIV on the immune system. Destroys T lymphocytes
Explain why those with HIV are more susceptible to opportunistic infections They have a weakened immune system
Name the cells that survive long term after clonal selection of B and T lymphocytes B and T lymphocytes
Describe one way s secondary response to same antigens differ 1. faster response 2. higher concentration of antibodies produed 2. antibodies stay higher for longer.
Repeated B or T lymphocyte cell division following binding to a specific antigen is called Clonal selection
State the protein B lymphocytes produce that is specific to a particular antigen antibody
When antibodies bind to specific antigens forming an antibody antigen complex this renders antigens harmless
Describe what happens after an antibody antigen complex is formed Phagocytes accumulate due to cytokines causing phagocytosis
State what type of lymphocytes causes allergy B lymphocytes
Explain how B lymphocytes cause allergy Hypersensitive and react to antigens on harmless substances.
