The authors have studied the arterial supply of splenic white pulp of the rat, by means of optic and scanning electron microscopy. This work shows that the marginal zone is a free and interstitial circulatory one that envelopes completely the periarterial lymphocyte sheets. These ones are vascular exclusion areas although crossed by vessels, probably impermeable, that pour their contents at the inner border of the marginal zone. It was impossible to find a so called "marginal sinus" neither a complete nor an incomplete one. These facts can explain and change some poorly understood immunological aspects.
