The arterial supply and venous drainage of the baroceptor areas of the cat and dog, and the human carotid sinus, are described from injected and cleared whole-mount preparations. There is an extremely rich vasa vasoral supply in these areas and a high venous to arterial ratio. The possibility that the vasa vasorum are modified to act as a �venous pump� is discussed. This microcirculatory pattern appears to be specific to baroceptor areas. This was demonstrated by examination of the structure of the vessel wall and by staining baroceptor nerve endings. Species differences are described. The method allows satisfactory photography and the paper is illustrated by photomicrographs.

    The contribution to the regulation of forearm blood flow (FBF) by different baroreceptor populations has previously only been studied over a limited range of stimuli. Therefore, FBF and R-R interval were recorded during neck suctions and neck pressures ranging from -60 to +40 mmHg. The change in...

    Mild (0 to –20 mmHg) lower body negative pressure (LBNP) has traditionally been considered to elicit reflex responses mediated by cardiopulmonary baroreceptors only, without any arterial baroreflex involvement. Mild LBNP has therefore frequently been used to study the influence of...

    Networks of blood vessels in normal and tumour tissues have heterogeneous structures, with widely varying blood flow pathway lengths. To achieve efficient blood flow distribution, mechanisms for the structural adaptation of vessel diameters must be able to inhibit the formation of functional...
