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.
The spleen and the kidney are two important organs found in the abdominal cavity of the human body. Their physiology is different because of their different functions in the body system. The spleen is a wedge-shaped lymphoid organ and is considered as the largest lymphoid mass located in the upper abdominal cavity, inferior to the diaphragm. Generally, it is 1 inch thick, 3 inches broad, and 5 inches long and weigh about 7 ounces. The spleen is made up of lymphatic cells.
