Question 2

the two collecting ducts that drain the lymphatic trunks

Answer 2

thoracic duct & right lymphatic duct

Question 3

how does increased hydrostatic pressure in tissue fluid affect the formation of lymph

Answer 3

Formation of lymph in the lymphatic capillaries increases due to increase in hydrostatic pressure in tissue fluid

The third line of defense.

Question 23

The hormone thymosin, secreted by the thymus, stimulates what cellular activity.

Answer 23

maturation of T cells

Question 24

Where may older red blood cells be destroyed

Answer 24

spleen

Question 25

primary immune response

Answer 25

B-lymphocytes give rise to plasma cells

Question 26

Second line of defense mechanisms

Answer 26

Chemical barriers - the enzyme lysozyme in tears, gastric juices in the stomach, salt from perspiration all attack pathogens

Question 27

Definition of immunoglobulin molecule

Answer 27

A type of antibody in plasma similar in structure to the antigen receptor molecules on the original B cells surface

Answer 31

something that causes disease

Question 32

riticuloendotheial tissue

Answer 32

type of tissue widely distributed phagocytic cells that remain in fixed position are found in this type of tissue

Question 33

Answer 33

antigen

Question 34

definition of gamma globulin fraction

Answer 34

plasma proteins

Question 35

Definition of vaccine

Answer 35

Includes the antigen that stimulate a primary immune response but do not produce the severe symptoms of disease

Question 36

definition of memory cell

Answer 36

Following a primary response the memory cells remain dormant but are able to respond to antigens in the future
