Across
- 3. Intestinal hormone stimulated by fat/protein; triggers bile and pancreatic enzymes
- 5. Lymphocyte that kills virus-infected and cancer cells via perforin
- 9. ~30 serum proteins causing opsonization, inflammation and lysis
- 11. Enzyme in saliva; breaks starch into disaccharides SAU7 Digestion
- 12. Hormone from G cells; stimulates gastric juice release
- 15. Duodenal enzyme that converts trypsinogen into active trypsin
- 16. Lymphocyte peptide blocking viral replication and tumour growth
- 17. Fixed tissue phagocyte engulfing large particles; presents antigens
- 19. Wave-like smooth muscle contractions that propel food along the gut
- 20. Thymus hormone aiding T lymphocyte maturation
- 21. Lymphocyte that differentiates into antibody-secreting plasma cells
- 23. Finger-like gut projections that maximise absorption surface area
- 24. Most abundant WBC; first responder engulfing small pathogens
Down
- 1. Cell-surface complex that displays antigenic fragments to T cells
- 2. Liver product emulsifying fats into micelles for lipase access
- 4. Lipid-protein cluster absorbed by lacteals after fat digestion
- 6. Lymphocyte activated by antigen-presenting cells; drives cellular immunity
- 7. Molecule that triggers a specific immune response
- 8. Semifluid stomach paste emptied into the small intestine
- 10. Immunoglobulin secreted by plasma cells; binds specific antigens
- 13. Active pancreatic protease; activates other pancreatic enzymes
- 14. Dormant cell enabling faster secondary immune response
- 18. Released by acidic chyme; prompts pancreas to secrete bicarbonate
- 22. Inactive stomach enzyme activated by low pH to digest proteins
