the carotid arteries
as insufficient oxygenated blood supply to brain
They supply the brain (and structures of the head, as well) with oxygenated blood.
The brain and heart require a constant supply of oxygenated blood. The brain is highly sensitive to oxygen deprivation, and even brief interruptions can lead to significant damage. The heart also needs a continuous supply of oxygenated blood to function effectively and maintain its rhythmic contractions. While the lungs and intestines also need blood supply, they do not require it as continuously as the brain and heart.
The internal carotid arteries and the vertebral arteries are the primary vessels that supply oxygenated blood to both sides of the brain. The internal carotid arteries branch into the anterior and middle cerebral arteries, while the vertebral arteries join to form the basilar artery, which supplies the posterior part of the brain. These arteries collectively ensure a rich supply of oxygenated blood, supporting brain function and health.
the artery(oxygenated blood) and vein(de-oxygenated blood)
Almost none. It does control its own flow, and it will speed the heart in anticipation of need, but that does not effect the actual flow of blood.
The lingual artery is the branch of the external carotid artery that supplies the tongue with oxygenated blood.
It pumps the oxygenated blood and sends it to your muscles and brain.
It pumps blood to and from your lungs to become oxygenated, and then pumps that oxygenated blood to your brain and the rest of your body for your cells to receive oxygen. Apparently it isn't pumping as much blood to your brain as it does most people, though.
The liver and kidneys are examples of organs that have dual blood supply. They receive blood from both the hepatic portal system and the hepatic artery (liver) and from the renal artery and renal vein (kidneys). This dual blood supply is important for their functions in filtering and processing blood.
The blood vessels around the brain help supply energy for your brain
When the blood supply to a portion of the brain is blocked this causes a stroke.
