The Brain is arguably the most important organ in the human body. It controls and coordinates actions and reactions, allows us to think and feel, and enables us to have memories and feelings—all the things that make us human.

⭐Brain Facts⭐
The brain is a complicated thing to understand, some scientists have spent their entire lives learning how the brain works.
There’s a video at the bottom with some cool facts about the brain, also check out twenty more facts below!

⭐Brain Information⭐
The human brain is more complex than any other known structure in the universe. Weighing in at three pounds, on average, this spongy mass of fat and protein is made up of two overarching types of cells—called glia and neurons—and it contains many billions of each. Neurons are notable for their branch-like projections called axons and dendrites, which gather and transmit electrochemical signals

The brain needs a steady flow of enough oxygen, glucose, and other nutrients. For that reason, it has a particularly good blood supply. Each side of the brain receives blood through three arteries:
The smallest branches (capillaries) of the arteries in the brain supply the brain cells with oxygen and nutrients from the blood – but they do not let other substances pass as easily as similar capillaries in the rest of the body do. The medical term for this phenomenon is the “blood-brain barrier.” It can protect the delicate brain from toxic substances in the blood, for example.
After oxygen has passed into the cells, the oxygen-poor blood flows away through the veins of the brain (cerebral veins). The veins carry the blood to larger blood vessels known as sinuses. The sinus walls are strengthened by a tough membrane (dura mater), which helps them keep their shape too. This keeps them permanently open and makes it easy for the blood to flow into the veins in the neck.
- In the front, the anterior cerebral artery supplies the tissue behind the forehead and under the crown (the top of the head).
- The middle cerebral artery is important for the sides and areas that are further inside the brain. The anterior and middle cerebral artery split off from the internal carotid artery, a major blood vessel in the neck.
- The posterior cerebral artery supplies the back of the head, the lower part of the brain, and the cerebellum. It is supplied with blood from the vertebral arteries, which are also major arteries of the neck.

⭐Keep Brain Healthy⭐
As we get older, it’s common to experience some cognitive decline like forgetting people’s names, losing track of time and other instances that we often chalk up to “senior moments.” However, making a few lifestyle changes can help keep your brain healthy well into old age.

⭐ What does the human Brain do?
The human Brain is the command center for the human nervous system. It receives signals from the body's sensory organs and outputs information to the muscles. The human brain has the same basic structure as other mammal brains but is larger in relation to body size than any other brains
