- Redistribution of blood flow
- Vascular shunt
- redistribution of blood flow to the areas where it is most needed
- the shunting of blood between competing tissues is achieved by
- the opening (dilating) and closing (constriction) of the arterioles supplying the blood entering the capillary bed
- control of blood shunting is regulated through the sympathetic nervous system
- the redistribution of blood is controlled primarily by
- Vasocontriction
- decrease blood flow through narrowing
- Vasodilation
- increase blood flow through widening
- Vasocontriction
- structures which aid blood redistribution are pre-capillary sphincters
- these are ring shaped muscles which lie t the opening of capillaries and control blood flow into the capillary bed
- Vascular shunt
