Abstract
In humorally isolated small intestine, the 10--20%--decrease in the perfusing blood volume against the background of augmented vascular resistance of the small intestine, induces different shifts of the latter's vascular capacitance. At the blockade of small intestine's beta--adrenoreceptors the decrease does not practically tell on the character of shifts in the intestine's resistance and capacitance while the blockade of alpha--adrenoreceptors abolishes the augmentation of these parameters.
