| Question | Answer |
|---|---|
| What are some ways to care for your immune system? | -eat healthy - personal hygiene - don't share body fluids - keep house clean - vaccinations up to date - rest and exercise |
| What is the definition of the immunes system? | The system that defends the body against infection and disease causing substances, such as bacteria, viruses and cancer cells |
| What is definition of antigen? | A non living invader in the body |
| What is pathogen? | an organism or substance that can cause a disease. |
| What are 4 ways to transmit infectious diseases? | - direct contact - indirect contact - water/food - animal bites |
| what is your first line of defence? | skin and lining of internal organs (gastric juice & cilia) |
| What is the second line of defence? | Immune response. Success depends on your body being able to tell which cells are from your body and which are not. |
| What is the Innate Immune response? | general and non-specific. Causes Inflammation. Usually used against things such as the common cold. |
| what is inflammation? | It's caused by the flow of cells, fluid and dissolved substances (swelling and redness). creates phagocytes to help fight pathogens and infection. |
| what are phagocytes? | White blood cells sometimes created by inflammation. |
| what is the acquired immune response? | very specific attack on antigen or pathogen. Both ways to send out this response include B-cells and T-cells (white blood cells) The first part is the B-cell. Second is the T-cell. This process can take up to one week. |
| What is the Innate Immune response? | quick and general way to fight pathogens. Usually fights bacteria and some viruses. First action is inflammation. Contributes to active immunity. |
| what is a virus? | non-living particles that reproduce when in a host cell. They are usually disease causing. |
| what is a disease? | any disturbance in the body. |
| what is active immunity? | When your body can remember what antibodies to use for a pathogen that has attacked it before. |
| what are antibodies? | used to fight antigens. They cover the antigen, preventing it from creating further infections. |
| what is a B-cell? | first part of the acquired immune response. B-cells locate antigens and produce antibodies. |
| what is a T-cell? | second part of the acquired immune response. Tow types of T-cells. Helper and killer. |
| what is a killer T-cell? | Works alone to directly attack pathogen. |
| what is a helper T-cell? | Is called on by B-cell when antigen or pathogen is there. |
| what are allergies? | a sensitivity to a certain substance. Cause histamines. |
| what is an allergen | anything that causes an allergic reaction. (pollen, cats, dust, food etc.) |
| what are histamines? | a chemical released into your body when you have an injury or need to fight something like allergens. |

| who was Jenner? | he resurfaced Montagu's observation by discovering that if you had had to cowpox you would not get to smallpox. |
| what are AIDS? | Acquired Immunodeficiency syndrome. caused bu HIV. No known cure. |
| what is HIV? | dangerous pathogen that attacks helper T-cells/ Because of the body can not protect itself against less harmful diseases. HIV is passed on from person to person by sex and drug needles. HIV always changes form. |
