Vascular shunt Flashcards
1
Q
What is the vascular shunt mechanism
A
Redistribution of blood during exercise
2
Q
Where does the blood go during exercise
A
Distributed to skeletal muscles to meet oxygen demands
Distribution to the skin to warm the skin, heat radiates off the body
Ditributed to the coronary arteries
Brain stays the same as it is constantly working
3
Q
How does the vascular shunt mechanism work
A
Exercise
CO2 detected by chemoreceptors
Impulse sent to vasomotor centre
Impulse sent down sympathetic nervous system
Stimulates pre capillary sphincters
Vasodilate at coronary arteries, skeletal muscles, skin
Vasoconstrict as non essential organs
