Abstract

The spontaneous contractions of the initial lymphatics of the bat's wing were observed to be modulated by changes in local blood flow. Lymphatic pressure and frequency of contraction were measured with the servo-null technique during the occlusion of the ulnar artery or vein. Lymphatic contractile activity was decreased during arterial occlusion but was increased during venous occlusion and postocclusion hyperemia. These changes in lymphatic activity are not consistent with the hypothesis that flow-associated changes in lymphatic contractile activity is mediated primarily by metabolic factors.
