Which cells are normally housed within lymph nodes?
NK cells and neutrophils
Lymphocytes and neutrophils
NK cells and complement cells
Lymphocytes and macrophages
The Correct Answer is D
A. NK cells and neutrophils: While NK cells can be found in lymph nodes, neutrophils are not typically housed in lymph nodes; they are more abundant in the bloodstream and tissues during acute inflammation.
B. Lymphocytes and neutrophils: Lymphocytes are indeed housed in lymph nodes, but neutrophils primarily migrate to sites of infection or inflammation rather than residing in lymph nodes.
C. NK cells and complement cells: Natural killer cells can be found in lymph nodes, but complement proteins are not cells; they circulate in the blood and become activated in response to pathogens.
D. Lymphocytes and macrophages: Lymph nodes primarily house lymphocytes (B cells and T cells) and macrophages, which play vital roles in the immune response by filtering lymph and

Correct Answer is D
Explanation
Trabeculae: These are thin connective tissue strands that extend from the capsule of the lymph node into the interior. They help to divide the lymph node into distinct compartments or regions, which include the cortex (outer area) and medulla (inner area). This compartmentalization is important for the organization and function of the lymph node, allowing it to efficiently filter lymph and facilitate the immune response.
Correct Answer is D
Explanation
A. Producing early induced proteins: While natural killer cells can produce cytokines, their primary function is not related to protein production.
B. Promoting opsonization of bacteria cells: Opsonization is primarily performed by antibodies and complement proteins, rather than natural killer cells.
C. Secreting signaling molecules: While natural killer cells do secrete signaling molecules (cytokines) to communicate with other immune cells, their main role is the direct destruction of infected cells.
D. Destroying virally infected cells: The primary function of natural killer cells is to recognize and eliminate virally infected cells and tumor cells, contributing to the innate immune response.
