Across
- 2. A place where lymphocyte first encounters an antigen
- 6. Site of gas exchange in the lungs
- 10. The resistance of members within a population to a disease
- 12. The concentration of circulating antibody to a specific antigen
- 14. Predominant antibody in other fluids (other than blood), can cross the placenta causing hemolytic disease of newborn, participates in all types of antibody reactions
- 15. antibodies, not directly getting sick, (can be transferred from mother to fetus via placenta or breastfeeding)
Down
- 1. The act of air coming in and out of the lungs
- 2. This results in the destruction of a pathogen before the onset of symptoms
- 3. Upper respiratory structures make up this part of the respiratory system
- 4. Weakened or dead components of a microorganism to stimulate the production of antibodies in the immune system
- 5. A nonspecific immune cell that looks for and destroys unwanted cells
- 7. Mostly in blood, agglutination processes functions in rejection of mismatched transfusions
- 8. Direct encounter with pathogen, being sick or getting vaccine
- 9. Results in the formation of a long-lived army of lymphocytes upon immune activation
- 11. Involves memory lymphocytes, shorter than primary response
- 13. Disease involving the destruction of helper T-cells, high susceptibility to other illnesses, resides in body fluids
