Which is not true of the blood flow routes in spleen?
A. In the closed circulation, capillaries branching from the penicillar arterioles connect directly to the sinusoids and the blood is always enclosed by endothelium.
B. In the open circulation, capillaries from about half of the penicillar arterioles are uniquely open-ended, dumping blood into the stroma of the splenic cords.
C. The small openings in the sinusoids of open system present no obstacle to platelets, to the motile leukocytes, or to thin flexible erythrocytes.
D. Removal of all RBCs and recycling of their iron are major functions of the red pulp.
