-Thymus
-Lymph nodes
-Spleen(slezina)

Question 3

Bone marrow

Answer 3

manufactures/forms WBCs

Question 4

Thymus

Answer 4

maturing of T-cells

Question 5

Lymph nodes

Answer 5

filters pathogens from the lymph and expose them to WBCs

Question 6

Spleen

Answer 6

filters blood from pathogens

Question 7

T-cells

Answer 7

-form and mature in thymus
-directly attack the cells
=>cell-mediated immunity

Question 8

B-cells

Answer 8

-formed in BM,mature in thymus
-produce proteins called antibodies(sevreted into nlood and other body fluids
=>humoral immunity(protilátková)
