Question
Chapter 14, Problem 1VC
Summary Introduction
To determine:
How abnormality in bone marrow and thymus can lead to immune deficiency.
Concept introduction:
B-cell and T-cell are the components of immune system. B-cells provide humoral immunity and are known to develop from hematopoietic stem cells present in bone marrow. T-cells provide cell-mediated immunity and are known to originate in the hematopoietic stem cells but mature in the thymus.

Match the lymphoid tissue to its function. Some answers may be used more than once. Some questions may have more than one correct response.
1. Transfers excess fluid in the blood to the lymphatic system2. Matures T cells3. Defends against pathogens entering the mouth or nose4. Protects against pathogens in the urinary tract5. Filters lymph

Secondary lymphoid organs, such as the lymph nodes, spleen, and mucosa-associated lymphoid tissues, each have distinct features that are important for their role in initiating immune responses focused on different anatomical compartments (i.e., the peripheral tissues, the blood, or the gastrointestinal tract, respectively). Yet these organs share some overall structural features, such as distinct T-cell and B-cell zones. One major difference between these organs is:
The presence versus the absence of macrophages and dendritic cells
Their function in bringing rare naive lymphocytes into contact with their specific antigen
The ability of lymphocytes to enter the organ from the blood
The mechanism by which antigens or pathogens enter the organ
The ability of naïve T cells to be activated and proliferate in the organ

" " TLRs act as an alarm system to alert both the innate and adaptive immune systems that an infection is brewing.
