<prompt> Blood in splanchnic area during exercise is decreased due to :Venoconstriction with decreased blood flowVenodilation with decreased blood flowVenodilation with increased blood flowVenodilation with normal blood flow  <response>: A i.e. Venoconstriction with decreased blood flow During vigrous exercise, constriction of vessels in splanchnic organ, and decreased blood storage in liver other poion of splanchnic bed occursQ, which may increase the volume of actively circulating blood, perfusion the muscles by as much as 30. Contraction of the capacitance vessels in the viscera can pump a litre of blood into the aerial circulation, in less than a minute.
