HBS 5.3
Lymphatic and Immune System
| Term | Definition |
|---|---|
| Thymus | Helps in the development of T-cells |
| Spleen | the blood of foreign cells and old red blood cells in need of replacement |
| Bone Marrow | produces new blood cells, both red and white |
| Liver | collecting and eliminating foreign compounds from the large volume of blood that passes through it |
| Tonsils | stop germs entering the body through the mouth or the nose |
| Lymph Nodes | Glands that usually enlarge in response to an infection and activate/produce specific B-cells |
| Type A can donate to ___ and recieve blood from ___ | donate to Type A, or AB and recieve from A or O |
| Type B can donate to ___ and recieve blood from ___ | donate to Type B, or AB and recieve from B or O |
| Type AB can donate to ___ and recieve blood from ___ | donate to Type AB and recieve from A, B, AB, or O |
| Type O can donate to ___ and recieve blood from ___ | donate to Type A, B, AB, or O and recieve from O |
| Type A contains ___ antigens and ___ antibodies | A antigens and anti-B antibodies |
| Type B contains ___ antigens and ___ antibodies | B antigens and anti-A antibodies |
| Type AB contains ___ antigens and ___ antibodies | A and B antigens and no antibodies |
| Type O contains ___ antigens and ___ antibodies | no antigens and anti-A and anti-B antibodies |
| Vaccination | works by introducing a killed, weakened, or partial form of the virus or bacteria so that the body can recognize the antigen and be able to produce a stronger immune response when exposed again in the future. |
| Parts of blood | Red blood cells, platlets, White Blood Cells, Plasma |
| Red Blood Cells | Carry oxygen through the body |
| Platlets | Help to form clots and scabs |
| White Blood Cells | Immune cells - many different types |
| Antibodies | special proteins that can target and inactivate specific antigens; produced by B-cells |
| Antigens | proteins that can be used to recognize forgein structures in the body |
| B-cells are made... | in the bone marrow but are activated in the spleen and lymph nodes |
| T-cells are made... | in the bone marrow but develop in the thymus |
| B- cell function | create antibodies for specific antigens, part of humoral immune response |
| T-cell function | recgonize and kill cells with foreign antibodies, part of cell-mediated immune response |
| During Incubation | The antigen is engulfed by a macrophage and is presented to a helper T cell, before illness |
| During the Prodromal period | The helper T-cell docks with a B cell and shows the antigen to the B cell, before illness |
| During the Period of Illness | The B cell clones itself into many plasma cells that are producing tons of antibodies specific to the antigen. Memory B cells form. |
| During the Period of Decline | Plasma cells stop producing antibodies and memory B cells remain, ready for another exposure to the antigen. After illness |
| During Convalesce | Antibody titre(count) begins to decline. After Illness |
| Secondary Exposure | Memory cells are activated, immune response is faster and stronger, illness will be shorter you may not feel sick at all |
| Humoral Immune Response | Response that is mediated by antibodies made by B-cells and is specific |
| Cell-mediated Immune Response | Response is mediated by T-cells and is non-specific. Attacks infected cells instead of specific pathogens |
