(3 cards)
1
Q
Vascular shunt
A
The redistribution of blood to where it is required
2
Q
Mechanisms of vascular shunt
A
Arterioles-vasodilate or vasoconstrict
Pre capillary sphincters (PCS)- vasodilate or vasoconstrict
3
Q
Vascular shunt during exercise
A
- receptors detect and infirm the VCC
- VCC decreases symptoms[athetic stimulation
- Vasodilation of PCS & arterioles to working muscles
- Increase blood flow to working muscles
-Increased sympathetic stimulation
-Vasoconstriction of PCS & arterioles to no essential organs
-Decrease blood flow to organs
