The red pulp of the spleen is most associated with which component?

Explanation:
The red pulp is where blood filtration and red blood cell turnover happen. It contains splenic sinusoids and the cords of Billroth filled with many red blood cells and macrophages. The macrophages phagocytose aged or damaged RBCs and help recycle iron, which is the hallmark function of the red pulp. This contrasts with the white pulp, which is lymphoid tissue focused on immune responses, and with the capsule, which is simply the outer connective tissue covering the spleen. So the red pulp’s defining role is filtering blood and removing old RBCs.
