The brain requires oxygen to generate the energy it needs to operate. Blood provides the necessary oxygen transport. Blocking the arteries would starve the brain of oxygen and the brain would rapidly start shutting down. Starve it of oxygen long enough (about one minute) and cells stop functioning properly and even start dying, escalating rapidly to whole brain death.
This is not a healthy thing to do. Do not try this at home.
What else can I help you with?
Do arteries carry blood away from the heart and why?
Yes arteries do carry blood away from the heart. They do this to feed the smaller tubes such as veins and capilaries. Then these smaller tubes transport blood to the body to give it oxygen and the nutrients it needs.
What happens to the human brain as one gets older?
As a person gets older, the human brains processing speed slows down and your memory begins to weaken. However, exercising the brain with stimulating exercises will help the brain to keep pace with aging.
What is the time frame for brain death due to lack of oxygen?
Most adults die after 10 minutes of having no oxygen to their brain, as their brain tissue immediately begins to die, and after 10 minutes, the brain tissue is too damaged, and they are brain dead.
What happens to the Nervous System as you age?
Aging produces various structural and functional changes in the nervous system, including: reduction in brain size and weight, reduction in number of neurons, decrease in blood flow to brain, changes in synaptic organization of the brain, and intercellular and extracellular changes in CNS neurons.
Can your brain ever run out of memory?
No, we can never run out of memory, our brains are always making new brain cells all the time, so no, it's impossible to run out of memory.No. Our body DOES NOT make new brain cells. There are only so many and they can be killed. But our brain can hold over 4 terabytes of memory. Meaning that the odds of you being able to fill the memory of your brain is very low. Even then, your brain categorizes your memories into short term and long term and when you learn more and more things, your brain will throw out old memories that you don't need and haven't used in a long time which is why we forget things.Short and simple, No, your brain cannot run out of memory.
What system does a stroke affect?
By definition a stroke affects the brain by blocking small arteries that carry blood to the cells and deliver nutrients and oxygen. These become blocked and the cells that the artery is leading to, die. A similar thing happens when arteries to the heart muscle cells that are blocked causing a heart attack.
What are blocked arteries called?
Blocked arteries are called coronary arteries. Carotid artery disease is another named for blocked arteries. This should be determined by a doctor.

Why are the coronary arteries so easily blocked by floating embolisms?
Why are coronary arteries so easily blocked by floating embolisms
What is the path of blood from the left ventricle to the brain?
Blood vessels that supply the brain are the two carotid arteries and the two vertebral arteries.- From the left ventricle, blood flows into the aorta and the common carotid arteries supply the frontal portion of the brain through the inner carotid arteries, which lead to blood vessels such as the three pairs of cerebral arteries (anterior, middle, posterior).- From the left ventricle, blood flows from the arch of the aorta into the paired subclavian arteries, and then to the vertebral arteries, which supply the rear and lower parts of the brain through the basilar artery (which ends at the posterior cerebral arteries).* Within the brain, cross-connections between these arteries (called the Circle of Willis) provide some redundancy should any of the arteries become severed or blocked.
What blocked arteries can be bypassed by using veins in the leg?
They are called left internal mammary arteries (LIMAs).
What arteries would be most likely blocked in someone with chest pain?
coronary arteries
Can you get an infarction with three blocked arteries?
absolutely! You can have an infarction with just one blocked artery
What two paired arteries enter the skull to supply the brain?
The anterior portions of the brain are supplied by the internal carotid arteries. The posterior portion of the brain is supplied by the vertebral arteries.
What can happen when blood supply to the heart is blocked-?
When blood supply to the heart is blocked what happens is a myocardial infarction which can result in death.
What is lack of blood to a tissue fed by blocked arteries?
infarct
Provides the brain with oxygen and nutrients?
Oxygen and nutrients are provided to the brain via the carotid arteries and vertebral arteries.
