Changes in the venous vessels capacitance in the cat forepaw in response to neurohumoral stimuli

The trend in changes of the cat forepaw vessels' capacity was found to practically not differ from the trend in shifts in the vena cava anterior basin's capacity: in both areas the capacity decreases in response to pressor neurogenic stimuli and decreases or increases under the effects of pressor and depressor humoral stimuli. The data obtained suggest that the trend in shifts of the vena cava anterior basin's capacity under the effects of pressor humoral stimuli mainly depends on the skin-muscular area's vessels, whereas the trend in shifts of the vena cava anterior basin's capacity under the effects of depressor humoral stimuli depends, apparently, on the shifts in the brain vessels' capacity function.
