Blood flow through the submandibular gland was studied in rabbits by the H2 gas clearance technique. By lowering the arterial pressure in the regional vessels supplying the gland, a corresponding decrease of the glandular perfusion rate was observed. During the pressor response elicited by the unilateral occlusion of the common carotid artery, a vasoconstriction developed in the vascular bed of the contralateral submandibular gland.
