CHAPTER 14: IMMUNE SYSTEM

Question 1

ECF- bloodstream

Answer 1

• blood
• plasma
• serum
• hematopoeisis
• stem cells
• leukocytes

Question 2

RES: reticuloendothelial system

Answer 2

• network of connective tissue fibers that connect w other cells of surrounding organs
• inhabited by phagocytic cells (mononuclear phagocyte system)
• macrophages ready to ATTACK and DIGEST microbes that pass 1st line of defense

Question 3

Blood and plasma

Answer 3

• plasma and formed elements (RBC/WBC/Platelets)

plasma: 92% water, metabolic proteins, globulins (antibodies), clotting factor, hormones

Question 4

serum

Answer 4

liquid part after a clot has formed

this is the plasma WITHOUT the clotting factors

Question 5

Hematopoeisis

Answer 5

production of RBC

produce blood and bone marrow cells (RBC, WBC, platelets, lymphocytes)

Question 6

Stem cells

Answer 6

undifferentiated cells
- precursor for RBC, WBC, platelets

Question 7

Leukocytes

Answer 7

• granulocytes and agranulocytes

Question 8

Granulocytes

Answer 8

lobed nucleus

• neutrophil
• eosinophil (destroy euk pathogens)
• basophil (release chem mediators)
• mast cell (1st LOD for local invasion)

Question 9

Agranulocytes

Answer 9

unlobed rounded nucleus

• lymphocytes: B and T cells
• monocytes/macrophage (largest WBC)

Question 10

Monocytes differentiate into…

Answer 10

macrophage= final differentiation of monocyte
dendritic= trap pathogen and help the immune response

Question 11

lymphocytes: T and B cell difference

Answer 11

B cell= humoral immunity, make antibodies
T cell= cell mediated immunity, kill foreign cells
