red pulp
C
lymph sinuses
D
medullary cords
Verified step by step guidance1
Understand the structure of the spleen: The spleen is an organ involved in filtering blood and immune response. It contains two main types of tissue: white pulp and red pulp.
Identify the function of white pulp: White pulp is associated with the immune function of the spleen. It contains lymphocytes suspended by reticular fibers, which are crucial for the immune response.
Differentiate between white pulp and red pulp: Red pulp is involved in filtering the blood and removing old or damaged red blood cells. It does not primarily contain lymphocytes suspended by reticular fibers.
Consider the role of lymph sinuses and medullary cords: Lymph sinuses are spaces within lymph nodes that allow lymph to flow through, while medullary cords are structures within lymph nodes containing lymphocytes and macrophages. These are not directly related to the spleen's structure.
Conclude that the areas of lymphocytes suspended by reticular fibers in the spleen are known as white pulp, based on their function and structure within the spleen.
