Compared with the brain, other organs of the human body are almost insignificant. Although the brain is also listed as an organ in a system, it is a leader beyond all organs. Other organs are not as important as the brain. The brain is a core. Because the brain is the center of human consciousness and subconscious. It is the brain, not other organs, that makes people the spirit of everything.

The brain consists of brain, cerebellum and brain stem. The brain is divided into left hemisphere and right hemisphere. Human intelligence, knowledge and judgment are all influenced and controlled by two battle balls in the brain. The brain occupies the upper part of the whole skull, from which we can know the importance of the brain. The volume of the cerebellum is only about one-eighth of that of the brain, and its main function is to maintain balance and coordinate muscle activities. The brain stem, also called the lower brain, contains the thalamus and hypothalamus that control hunger, thirst, sleep and sexual behavior; And the midbrain and pons that transmit pulses between different parts of the brain; There is also the medulla oblongata which controls breathing, blood pressure, heartbeat and other important functions. These parts make up the human brain, which makes people smart, agile and full of vitality.
