answer

all of the listed responses are correct.

i dont know yet

Explanation:

• First option: Splenic cords are part of red pulp, not white pulp. White pulp is related to lymphoid tissue.
• Second option: Since first and fourth options are wrong, “All of the listed responses are correct” is incorrect.
• Third option: Red pulp has blood cells (erythrocytes, leukocytes etc.) and macrophages (fixed and free) which is correct. Macrophages in red pulp phagocytose old erythrocytes, debris etc.
• Fourth option: Lymphoid nodules are part of white pulp, not red pulp. Red pulp is more about blood - related functions like filtering blood.

Answer:

The cell population of the red pulp includes all of the normal components of the circulating blood, plus fixed and free macrophages.
