  1. 2. Inflammation that is ongoing and is caused by foreign bodies, ongoing defense against pathogens (like allergies), autoimmune diseases.
  2. 4. Cells created in the thymus that produce substances that attack infected cells in the body.
  3. 8. The production of lymphocytes from lymphoid stem cells
  4. 10. Chemicals released by the immune system communicate with the brain and is produced by many different cells
  5. 11. Masses of lymphatic tissue in the back of the oropharynx. They function to capture pathogens and phagocytize foreign substances.
  6. 13. They are lipid molecules that trigger and sustain inflammatory responses. They attract neutrophils from the blood to the site of injury.
  7. 14. Cells that release chemicals (such as histamine) that promote inflammation.
  8. 15. Are made up of Neutrophils which are bacteria phages and Eosinophils which protect us from parasitic infection
  9. 17. Amoeboid cells that develop from monocytes, that roam connective tissue and engulf foreign particles and debris of dead cells.
  10. 19. Cells manufactured in the bone marrow that create antibodies for isolating and destroying invading bacteria and viruses.
  11. 21. Bean-shaped filters that cluster along the lymphatic vessels of the body. They phagocytize foreign substances. They function as a cleanser of lymph as wells as a site of T and B cell activation.
  12. 22. An organ that is part of the lymphatic system; it produces lymphocytes, filters the blood, stores blood cells, and destroys old blood cells.
  13. 23. Chemical stored in mast cells that triggers dilation and increased permeability of capillaries.
  14. 25. Areas that ling the mouth, noser, lungs, stomach, intestines etc.. These membrane line the boy cavities and secrete mucus. Mucus lubricates the surface of the membrane and traps microbes and foreign particles
  15. 27. Inflammation occurring for a limited time period; rapidly developing
  16. 28. Cell movement that occurs in response to chemical stimulus
Down
  1. 1. A group of bioactive, hormone-like chemicals derived from fatty acids that have a wide variety of biological effects including roles in inflammation, platelet aggregation, vascular smooth muscle dilation and constriction, cell growth, protection of from acid in the stomach, and many more.
  2. 3. Cells that develop from B cells and produce antibodies.
  3. 4. An immune organ located near the heart. The thymus is the site of T cell maturation and is larger in children and adolescents.
  4. 5. the watery fluid in the lymph vessels collected from the tissue spaces
  5. 6. The process of which cells attach to the surface or to another cell
  6. 7. Enzyme that breaks down bacterial cell walls.
  7. 9. Proteins (cytokines) secreted by T cells and other cells to aid and regulate the immune response
  8. 12. Immune system cell responsible for suppressing viruses and destroying tumor cells
  9. 13. Functions to make tears. Tears are used to lubricate the eyes and with the aid of the eyelids, prevent microbes from becoming established on the eye. Tears also wash away foreign particles like dust.
  10. 16. proteins in the blood that act a s a defense mechanism against pathogens and help antibodies kill their target
  11. 18. Is a Phagocytic cell that surrounds and engulfs a target particle or microorganism
  12. 20. vessels that receive lymph from the lymph capillaries and circulate it to the lymph nodes
  13. 24. the ingestion of bacteria and other material by phagocytes
  14. 26. The skin, mucous membranes, and secretions help remove bacteria and fungi
