Herein, what increases cerebral blood flow?
Acute hypoxia causes an increase in cerebral blood flow via direct effects on vascular cells of cerebral arteries and arterioles. Hypoxia-induced drop in ATP levels opens KATP channels on smooth muscle, causing hyperpolarization and vasodilation .
Which vein carries blood to the brain?
Blood is supplied to the brain, face, and scalp via two major sets of vessels: the right and left common carotid arteries and the right and left vertebral arteries. The common carotid arteries have two divisions. The external carotid arteries supply the face and scalp with blood.
