Patterns of flow were recorded from individual capillaries of mesentery and muscle during autoregulation and reactive hyperemia. In cat mesentery at normal arterial pressure capillary blood flow was often periodic in nature. When arterial pressure was reduced periodicity was abolished and in certain cases mean flow increased. Elevation of venous pressure at this time caused restoration of flow periodicity and simultaneously a large fall in mean flow. Vasomotion and autoregulation in mesentery appear to be dependent on intravascular pressure per se. In cat sartorius muscle substantial increase in flow was seen in most capillaries during reactive hyperemia. In certain capillaries the pattern resembled the gross flow pattern while others showed a brief hyperemia and then a period of flow arrest that is presumably due to a strong precapillary vasoconstriction. The latter response is suggestive of a myogenic control while the former may be due to accumulation of metabolites. In frog pectoralis muscle reactive hyperemia was very prolonged in comparison to cat sartorius muscle. The general pattern of flow was consistent with the notion of a strong metabolic control mechanism. The three tissues studied provide examples of strong myogenic, strong metabolic, and combined metabolic and myogenic control of the microcirculation.
