|
What type of cells do do lymph structures contain, where are they located, and what do they do?
|
T-lymphocytes: located in thymus gland, they kill foreign invaders (antigen)
Blympohcytes: Produced in bone marrow, produce soluble proteins called "antibodies" that bind to and immobilize the foreign or abnormal agent, thus damaging it or identifying it to to other elements of the immune system. and macrophages |

|
|
|
The cells in the lymph system constantly do what?
|
monitor the blood and interstitial fluid for foreign antigens
|
|
|
What is involved in the immune response against antigens?
|
(B-lymphs produce antibodies that bind to and immobilize the foreign or abnormal agent, thus damaging it or identifying it to other elements of the immune system,
T-lymphs attack and destroy the antigen directly. B-memory and T-memory cells, which remember the past antigen encounters and initiate an even faster and more powerful immune response should the same antigen appear again. |
