**[B Cells]** B Cells Develop in the **\_\_\_\_\_\_\_\_\_\_\_\_\_**, leave after maturation -- reside in the lymph nodes and spleen. B cells recognise free **\_\_\_\_\_\_\_\_\_\_\_**straight away (unlike T cells which rely on Antigen Presenting Cells). The B cell's main function is to produce **\_\_\_\_\_\_\_\_\_\_\_\_\_** against foreign antigens. Their major role is in the **\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_** immune response. Antibody response is usually dependant on **\_\_\_\_\_\_\_** help[ ] Activation by foreign antigens leads to **\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_** into plasma cells** **which release antibodies or memory B cells. **\_\_\_\_\_\_\_\_\_\_**cells are survivors of previous infection and remain for the long-term, continuing to express unique **\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_** at the tips of the antibody on their cell membrane. They are involved with the **\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_** immune response. These B cells respond to re-exposure of the **\_\_\_\_\_\_\_\_\_\_\_\_\_**antigen, to eliminate them. **\_\_\_\_\_\_\_\_\_\_\_\_\_\_** cells (*effector cells*) secrete millions of antibodies which have the unique antigen binding properties as the receptor molecules found on the surface of the original B cell. They will only combine with the antigen which originally activated the B cell. Antibodies circulate in the **\_\_\_\_\_\_\_\_\_\_\_\_\_\_** (blood, bile, phlegm). When they meet their specific antigen, they will **\_\_\_\_\_\_\_\_**onto them. This leads to the **\_\_\_\_\_\_\_\_\_\_\_\_\_\_**of the antigen in various ways such as agglutination, neutralization, immobilization, **\_\_\_\_\_\_\_\_\_\_\_\_\_** and activation of the complement system. Plasma B cells are generally short lived and do not express antigen-binding receptors. Once the foreign agent has been destroyed, plasma cells undergo **\_\_\_\_\_\_\_\_\_\_\_\_\_** (cell death) [Select the correct word/s to fill the blanks:] ** ** ** **
