SOLUTION - UTA POLLOCK (IMMUNE,
RESPIRATORY, DIGESTIVE, NUTRITION) 2024/2025
primary immune organs - Correct Answer Bone marrow - Immune cell production, B cell maturation



Thymus - T cell maturation



Secondary immune - Correct Answer •Sites where most immune responses occur.

•Nodes = focus on lymph

•Spleen = focus on blood

•Tonsils = focus on respiratory tract & pharynx

Appendix & Peyer's Patches = focus on GI tract



Neutrophils - Correct Answer •Phagocytosis.

•Respond quickest to bacterial infection.



Eosinophils - Correct Answer •Attack endoparasites.

Contribute to allergic reactions



basophils - Correct Answer •Release pro-inflammatory chemicals.

•Contribute to allergic reactions.



monocytes - Correct Answer •Differentiate into macrophages.

•Can be wandering or fixed.



Lymphocytes - Correct Answer •B cells, T cells, memory T & B cells

•B = antibodies

•T = helper, regulatory, cytotoxic



Mast cells - Correct Answer •Release pro-inflammatory chemicals.

•Contribute to allergic reactions.

,dendritic cells - Correct Answer antigen-presenting cells



natural killer cells (NK cells) - Correct Answer play an important role in the killing of cancer cells and
cells infected by viruses



innate immunity - Correct Answer •Non-specific

•Immediate response (1st and 2nd lines)

•No immunological memory

-first and second line of defense to stop pathogens

tightly to PAMPs



Pathogen-associated molecular patterns (PAMPs) - Correct Answer help the innate immune system
recognize pathogens and bind to TLRs



How many TLR types - Correct Answer 11



Macrophages - Correct Answer develop from monocytes, are the largest leukocytes and primary
phagocytic cells



free macrophages - Correct Answer wander through tissue spaces



fixed macrophages - Correct Answer residents in tissues and organs



AIDD - Correct Answer Adherence

Ingestion

Digestion

Destruction



Antigen presenting cells - Correct Answer dendritic cells, macrophages, B cells



antigen presenting cells - Correct Answer insert digested pieces of the pathogen into specific
membrane proteins for presenting to/activation of other immune cells



respiratory burst - Correct Answer Helper T cells cause release of enzymes in macrophages which kill
pathogens resistant to lysosomal enzymes



natural killer cells (NK cells) - Correct Answer -Nonphagocytic, large granular lymphocytes that police
blood and lymph
