A
initiate immune responses by producing lymphocytes
B
filter and remove old or damaged red blood cells
C
store red blood cells for later release
D
produce platelets for blood clotting
Verified step by step guidance1
Understand the anatomy and physiology of the spleen: The spleen is divided into two main regions, the white pulp and the red pulp, each with distinct functions.
Focus on the white pulp: The white pulp is primarily involved in immune functions. It contains lymphoid tissue, which is rich in lymphocytes (a type of white blood cell).
Learn the role of lymphocytes: Lymphocytes are responsible for initiating immune responses. They detect and respond to pathogens, such as bacteria and viruses, by producing antibodies and activating other immune cells.
Differentiate the functions of the red pulp: The red pulp is responsible for filtering and removing old or damaged red blood cells, storing red blood cells, and recycling iron. This is distinct from the immune function of the white pulp.
Match the correct function to the white pulp: Based on the information above, the white pulp's primary role is to initiate immune responses by producing lymphocytes, which distinguishes it from the other options provided.
