Immune system

3. Globulin protein which binds and transports iron in plasma
6. Type of immunity relying on antigen-specific antibodies secreted by plasma cells
7. Several plasma proteins circulating in the blood under their inactive form. Once activated by a pathogen, they lead to a cascade of reactions promoting inflammation, triggering cytolysis (via a membrane attack complex), enhancing phagocytosis, and facilitating immune clearance.
11. Enzymes that catalyze the destruction of the cell walls of certain bacteria, present in body secretions (tears, sweat, etc.).
12. Local immune reaction to injury or infection leading to the body part being red, hot, swollen and painful.
13. Proteins able to inhibit virus replication.

1. Abnormally high body temperature.
2. Fluid of very low pH secreted by the lining of the stomach, containing digestive enzymes.
4. Slightly acidic film covering the skin, composed of a mix of sweat and sebum.
5. Cells able to ingest cell debris or pathogens to kill and digest them.
8. Membrane composed an epithelial and connective tissue, containing mucous glands, lining body cavities opened to the outside.
9. Type of cells that are part of the innate immune system, able to directly kill foreign cells (recognized as non-self).
10. Type of immune response that does not involve antibodies, but rather the activation of antigen-specific T-lymphocytes.
14. Largest organ of the body, part of the first line of immune defenses.
