Vascular Shunt Flashcards
1
Q
Vascular shunt is…
A
The redistribution of blood
2
Q
What is the vascular shunt controlled by?
A
The Vasomotor Control Centre
3
Q
The vasomotor control centre receives impulses from the receptors
A
Like the Chemoreceptors that detect chemical changes in the blood
4
Q
Sympathetic stimulation will then either be…
A
Increased or decreased to alter the levels of vasoconstriction
5
Q
Increased stimulation leads to?
A
Vasoconstriction of the pre-capillary sphincters, which limits blood flow
6
Q
Decreased stimulation causes?
A
Vasodilation of the pre-capillary sphincters which increases blood flow
7
Q
Vascular shunt allows the body to?
A
Exchange gasses, nutrients and waste
