Blood flow through the Reconditioning organs should be supplied constantly and adequately: comment
Ans-No.not necessary. Reconditioning organs like G.I.T, skin and kidney can tolerate significant reductions in blood flow for a considerable length of time. Because they receive blood flow in excess of their own needs. They can withstand temporary reductions in blood flow much better than other organs (heart and skeletal muscle) that do not have this extra margin of blood supply, brain in particular suffer irreparable damage when transiently deprived of blood supply. During exercise some of the blood that normally flows through G.I.T, kidney is diverted instead to skeletal muscle. Likewise blood flow through skin is markedly decreased during exposure to cold to conserve heat.
