Abstract

Afferent and efferent units of immune system of mucous membrane of the small intestine in white outbred rats have been studied light-and electron microscopically. On the basis of the received findings it was established that afferent unit stimulates and regulates T-, B - blast’s coo relation. Action of epithelium, stimulated T- and B - lymphocytes and cells of connective tissue has been integrated in efferent unit.
