5. Donor — O- blood type that can be given to anyone
7. Tissue — Tissue containing lymphocytes and immune cells
9. Gland — Gland in the chest that produces and matures T cells (especially in children)
10. — Protein in blood plasma that attacks and neutralizes foreign antigens

12. — Organ that filters blood, produces lymphocytes, and stores blood cells

7. Capillaries — Tiny vessels that collect tissue fluid and begin the lymphatic system
8. — Destruction of red blood cells (occurs with incompatible blood transfusions)
10. — Protein on the surface of cells that triggers an immune response
13. System — Network of vessels and organs that filters fluid and fights infection
