Across
  1. 3. B-Cells get primed by antigens in this lymphatic structure
  2. 4. Antigen-presenting-cell, ie., macrophages, dendrictic cells and B-Lymphocyte
  3. 6. Major histocompatibility complex I. Every cell of the animal's body has this marker, except red-blood-cells
  4. 8. Immunity developed by T-Cells
  5. 9. The ability of B-Cells and T-Cell to elaborate an immune reaction after being primed
  6. 11. Immunity developed by B-Cells by producing antobodies
  7. 13. T-Cell get primed in this gland by the antigen
  8. 14. Animals are born with this line of defense
  9. 15. An antigen coming from outside of the animal's body and presented to the immune system by MHC II

  1. 1. A substance produced by B-Cells that binds to antigens. By biding to antigens, antibodies can destroy it or mark it as bad
  2. 2. Similar clone dells generated after a mitotic division during the priming process in both, T and B- Cells
  3. 4. Animals get this line of defense after they are born by being exposed to antigens
  4. 5. Major histocompatibility complex II. APCs are the only ones having these markers in their cell membranes
  5. 7. An antigen produced within the animal's body and presented to the immune system by MCH I.
  6. 10. A process by which T-Cells and B-Cells get "educated" to attain immunocompetence
  7. 12. A foreign or self particle that can provoke an immune reaction, sometimes a disease
