Blood flow is the continuous circulation of blood in the cardiovascular system. This process ensures the transportation of nutrients, hormones, metabolic wastes, O2 and CO2 throughout the body to maintain cell-level metabolism, the regulation of the pH, osmotic pressure and temperature of the whole body, and the protection from microbial and mechanical harms.
The science dedicated to describe the physics of blood flow is called hemodynamics. For the basic understanding it is important to be familiar with anatomy of the cardiovascular system and hydrodynamics. However it is crucial to mention that blood is not a Newtonian fluid, and blood vessels are not rigid tubes, so classic hydrodynamics is not capable of explaining hemodynamics.
Blood is composed of plasma and formed elements. The plasma contains 91.5% water, 7% proteins and 1.5% other solutes. The formed elements are platelets, white blood cells and red blood cells, the presence of these formed elements and their interaction with plasma molecules are the main reasons why blood differs so much from ideal Newtonian fluids.
The brain is an organ that serves as the center of the nervous system in all vertebrate and most invertebrate animals. Only a few invertebrates such as sponges, jellyfish, adult sea squirts and starfish do not have a brain; diffuse or localised nerve nets are present instead. The brain is located in the head, usually close to the primary sensory organs for such senses as vision, hearing, balance, taste, and smell. The brain is the most complex organ in a vertebrate's body. In a typical human, the cerebral cortex (the largest part) is estimated to contain 15–33 billion neurons, each connected by synapses to several thousand other neurons. These neurons communicate with one another by means of long protoplasmic fibers called axons, which carry trains of signal pulses called action potentials to distant parts of the brain or body targeting specific recipient cells.
Physiologically, the function of the brain is to exert centralized control over the other organs of the body. The brain acts on the rest of the body both by generating patterns of muscle activity and by driving the secretion of chemicals called hormones. This centralized control allows rapid and coordinated responses to changes in the environment. Some basic types of responsiveness such as reflexes can be mediated by the spinal cord or peripheral ganglia, but sophisticated purposeful control of behavior based on complex sensory input requires the information integrating capabilities of a centralized brain.
Khan Academy is a non-profit educational organization created in 2006 by educator Salman Khan with the aim of providing a free, world-class education for anyone, anywhere. The organization produces short lectures in the form of YouTube videos. In addition to micro lectures, the organization's website features practice exercises and tools for educators. All resources are available for free to anyone around the world. The main language of the website is English, but the content is also available in other languages.
The founder of the organization, Salman Khan, was born in New Orleans, Louisiana, United States to immigrant parents from Bangladesh and India. After earning three degrees from the Massachusetts Institute of Technology (a BS in mathematics, a BS in electrical engineering and computer science, and an MEng in electrical engineering and computer science), he pursued an MBA from Harvard Business School.
In late 2004, Khan began tutoring his cousin Nadia who needed help with math using Yahoo!'s Doodle notepad.When other relatives and friends sought similar help, he decided that it would be more practical to distribute the tutorials on YouTube. The videos' popularity and the testimonials of appreciative students prompted Khan to quit his job in finance as a hedge fund analyst at Connective Capital Management in 2009, and focus on the tutorials (then released under the moniker "Khan Academy") full-time.
Şo finally here is the video from my nervous system series about cerebral circulation and blood supply to the brain as well as circle of willis http://www.AnimatedAnatomy.com/ - Click Here The main point of this lesson is the circle of willis with two carotid arteries and two vertebral arteries that bring to blood to it. Further important arteries in the circle of Willis are the anterior cerebral artery and the middle cerebral artery that are connected with each other trough the anterior communicating arteries and which are also both connected with the posterior cerebral artery trough the posterior communicating artery. There are also arteries that supply the cerebellum and the brainstem and here I have mentioned the basilar artery and the pontine arteries along with the superior cerebel...

www.DrJones.TV is a website dedicated to the busy people of the world on how to lose weight, increase energy and maximize their health while on the go. In this video Dr. Jones explains 3 factors that reduce blood flow to the brain and 3 natural factors that will increase blood flow to the brain. Increasing bloodflow will increase oxygen saturation to neuronal tissues in the CNS. This helps the brain function at a higher level. When your brain is functioning at a higher level you can become far more productive. For more information for quick tips on how to transform your health go to: www.DrJones.TV

By tuning into the Schumann Resonance, the body benefits from this healing frequency and can more effectively rebuild and repair itself. Binaural beat brainwave entrainment technology can induce a specific brainwave state in the listener's brain. These artificially induced changes in the brainwave state will quickly and reliably generate a temporary change in the consciousness of the listener. This is a session which ramps down to the Schumann Resonance frequency, or 7.83 Hz. Research done with Zen meditators shows that 7.83 is a significant frequency, and other research indicates that stimulating the Schumann frequency results in more blood flow in the brain than any other frequency.
