The blood flow to the brain must be maintained in order for the vital functions of the body to be carried out, as the brain needs blood, which contains a large amount of oxygen, in order to nourish the nerve cells inside the brain. This causes many health problems, and blood circulation is the process of flowing blood that contains a percentage of nutrients, glucose and oxygen to the brain, through blood vessels and arteries so that the brain is provided with the necessary food and energy to perform all the vital functions of the body.
