vertebral arteries pass through foramen magnum and reach the inferior of the brain & unite to from the basilar artery. The vertebral artery supplies the posterior of the brain. Basilar atery branches into posterior cerebral artery & cerebellar arteries that supply the cerebellum & pons. Common carotid arteries divide & the internal carotid supplies structures internal to the skull
A blood cell must pass through two heart valves to travel from the brain to the lungs. As it exits the brain through the superior vena cava, it passes through the tricuspid valve, then through the pulmonary valve to reach the lungs for oxygenation.
A coronal plane through the head passes through the skull, brain, eyes, ears, nose, and mouth.
The brain uses about half of the oxygen taken in. Actually the real answer is because the brain is extremely sensitive to changes in its circulatory supply. An interruption of circulation for several seconds will produce unconsciousness and after 4 minutes there may be some permanent brain damage.
Yes, emboli in the bloodstream can potentially pass through the blood-brain barrier and cause an ischemic stroke by blocking blood flow to the brain tissue. This can lead to serious neurological deficits if not promptly treated.
Yes, nicotine is able to pass through the blood-brain barrier, which is why it can have effects on the brain and central nervous system. This property contributes to the addictive nature of nicotine.
The shrimp's food passes through its brain on the way to its stomach. This happens because the shrimp's brain and esophagus are connected.
foramen lacerum
Internal carotid artey passes through the carotid canal and takes blood to the brain
The vertebral artery passes through the transverse foramina of the cervical vertebrae. These arteries supply blood to the brain and spinal cord.
A blood cell must pass through two heart valves to travel from the brain to the lungs. As it exits the brain through the superior vena cava, it passes through the tricuspid valve, then through the pulmonary valve to reach the lungs for oxygenation.
you die or end up a vegetable, unless you're really lucky!
the carotid artery passes through the carotid canal to the brain
Blood circulates oxygen and nutrients through the brain.
Blood circulates oxygen and nutrients through the brain.
you can have a stroke because not enough blood is running through your body, yet alone to your brain.
The blood-brain barrier, via the blood stream.
It gets into the brain quickly because the brain gets a rich blood supply and because alcohol is able to diffuse across the blood-brian barrier easily due to being not strongly polar.
