What is the flow of brain blood?
Cerebral blood flow, or CBF, is the circulation of the blood of the brain. Blood flows into the brain of vertebrae and cervical artery in the throat and leaves mainly through the inner jugular, which is also found in the throat. Inside the brain there is a brain circulation inside the brain blood vessels, while the total flow is regulated to remain at a constant level. At the same time, blood supply to different parts of the brain varies according to the amount of activity. Blood pressure in arteries and veins and thickness or blood viscosity affects the total flow. In addition, small arteries in the brain can be reduced or dilated and the overall pressure inside the skull may change. All these elements interact to maintain the overall blood flow of the brain at a constant level. The pressure of the blood flow is sometimes referred to as brain perfusion pressure. When carbon dioxide pressure decreases as it can happen if people hyperventilation, brain blood flow decreases. This is because the low level of carbon dioxide causes the brain blood vessels to restrict so that for brain tissue is to the displayThe ozni less blood and man feels dizziness and dizziness.
changes in brain blood flow in different areas of the brain are associated with metabolic activity with active areas in which tissues occupy more glucose, which is in places with higher blood flow. The exact mechanism that happens is still not fully understood. Perfusion scanning is a technology using technology such as MRI or magnetic resonance imaging, creating brain images showing an increase in blood flow in such areas. These images can be used to demonstrate which parts of the brain are involved in performing certain activities, and can also help understand diseases such as Alzheimer.
Using imaging techniques, brain blood flow was found in conjunction with a number of different conditions, including hypothyroidism, where the thyroid does not create enough thyroid hormone. Here was found reduced supplied in certain areas of the brainBlood, including those related to memory and attention, which could lead to some symptoms of the disease. Hypothyroidism can be treated with the use of thyroid hormones to replace the missing natural hormones.
