When core perfusion decreases, where is blood preferentially shunted to?

Explanation:
When the body detects that core perfusion is dropping, it prioritizes keeping blood flowing to the most vital organs. The brain is highly sensitive to reduced blood flow, so the body redirects blood toward it (and to the heart) by constricting vessels in nonessential areas. This means skin, kidneys, and other peripheral tissues receive less blood, while cerebral perfusion is preserved. So the brain is the organ that receives the relative increase in blood flow under these conditions.
