Hint: In an adult human, arteries deliver glucose and other nutrients through the blood where a definite amount of the total cardiac output is delivered to the brain. This mechanism is the part of cerebral circulation which consists of a network of cerebral arteries and veins.
Complete answer:
Concerning the unstopped blood supply, the brain is a sensitive part of our body and it gets damaged easily from any stoppage in the blood supply. To deliver uninterrupted blood supply to the brain there is a cerebral circulation mechanism through which about 750 ml of blood is delivered to the brain per minute.
Additional information:
1) Cerebral circulation consists of a network of cerebral arteries and veins through which the oxygenated blood is supplied and the deoxygenated blood from the brain is returned.
2) There are some safeguards present in the cerebral circulatory system that ensure the auto-regulation of blood flow in the related blood vessels and when any of these safeguards fail, it results in a stroke.
3) The volume of blood that is in circulation in the cerebral circulatory system is called cerebral blood flow.
4) The major waste materials that veins carry away from the brain include lactic acid, carbon dioxide, and other metabolic products.
A representative diagram of the cerebrovascular system has been given below –
So, the correct answer is ‘750 ml’.
Note:
The cerebral circulation is divided into anterior and posterior segments where the anterior segment involves internal carotid arteries and the posterior segments involves the vertebral arteries.
Bilateral posterior communicating arteries make the interconnections between the anterior and posterior segments of the cerebral circulation and are said to provide a backup circulation to the brain.
