Allow the clams enough time to open their shells-this will be indicated by a burst of steam and popped-open shells, anywhere from 2â3 minutes to 5-10 minutes, depending on the type of clams. If some don't open in this time, discard them as they probably were already dead.
Spleen, lymph nodes, adenoids, tonsils are the encapsulated secondary lymphoid organs. Mucosa associated lymphoid tissue distributed throughout the body such as alimentary canal, respiratory and urinogenital tracts etc. are the diffused secondary lymphoid regions.
lymphocytes bone lymph nodes. The organs of the immune system either make the cells that participate in the immune response or act as sites for immune function.These organs include the lymphatic vessels, lymph nodes, tonsils, thymus, Peyer's patch, and spleen.The lymph nodes are small aggregations of tissues interspersed throughout the lymphatic system. White blood cells (lymphocytes) that function in the immune response are concentrated in the lymph nodes.Lymphatic fluid circulates through the lymph nodes via the lymphatic vessels. As the lymph filters through the lymph nodes, foreign cells of microorganisms are detected and overpowered.he lymph nodes are small aggregations of tissues interspersed throughout the lymphatic system. White blood cells (lymphocytes) that function in the immune response are concentrated in the lymph nodes. Lymphatic fluid circulates through the lymph nodes via the lymphatic vessels.
