The is a primary lymphatic structure responsible for helping general T lymphocytes to mature and to be trained to recognize “self” antigens, so that when they are attacking pathogenic material, they don’t attack the host’s own cells.

Condylar joints are:

Movement of a body part toward the main axis of the body is called:

Binding of antibodies to antigens can cause which of the following?

In order for a helper T cell to be activated to detect the presence of its specific antigen in the tissues, and then activate cytotoxic T cells and B cells, it must first have that antigen (from the pathogen) presented to it by an antigen presenting cell on that cell’s surface markers called:

Which of the following would not be able to occur in a disease in which plasma B cells were not producing antibodies appropriately?

The submucosa in the lining of the wall of the small intestine is protected from transmigration of pathogenic agents ingested orally by nodules of nonspecific immune tissue called mucosa-associated lymphoid tissue (MALT), or:

Lymph is an exudate of blood plasma that is collected in lymphatic conduits of various sizes. On its way back to the blood, it passes through and is filtered by immune cells in ______ for any pathogenic material it might contain.

______ are cytokines (and proteins) produced by virus-infected cells to slow viral protein synthesis and resultant replication within themselves, and also are released from the cell to enhance phagocytosis by macrophages.
