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.
Blood, Veins, and Oxygen flowing to the Brain.
mammals have closed circulatory system and further double circulatory system.
Yes but only to a degree. Removing a human brain from the skull is very difficult if not impossible to do without somedamage. Also, keeping sufficiently it oxygenated and supplied with nutrients is equally difficult with current technology. It can however be kept in cryogenic stasis.
The Brain That Wouldn't Die
with proper diet and exercise
One advantage of the double closed circulatory system is that the blood is kept inside arteries or veins all the time. This stops the blood mixing with other bodily fluids and helps with the transport of the blood around the body. Another advantage of the double closed compared to the open system is that in the double system the blood is always kept at a high pressure. This is an advantage as the high pressure of the blood means that the blood can travel faster around the body and deliever more oxygen to the body's cells.
you know that dalek bit of him at the bottem like a weel chair... that's his life support system
A brain can be kept alive in a jar with a nutrient-rich solution that provides oxygen and essential nutrients to maintain its metabolic functions. This solution can help keep the brain's cells alive and functioning, though it cannot replicate the complex interactions and regulatory mechanisms of a living body. Ethical and legal considerations also need to be taken into account when discussing such experiments.
If your brain shuts down completely you also cease to breath and therefore die. You may continue to live or breath by mechanical means or a respirator. But if your kept alive by a respirator and your brain is really dead are you really living?
An infection, but not just any infection. In a normal infection, the baceria are kept in the infection site. If it breaks through a break in the circulatory system, it's called bacteriemia and it's one of the most deadly infections since it can spread to multiple organs, this is called septicemia.
Racism should never be kept alive. It is a very unfair belief, and very hurtful to those that are being targeted.
