When blood flow to the brain is interrupted, less oxygen and glucose reach the brain. This causes brain damage and neurological problems.
<h3>Blood flow to the brain</h3>
Blood circulation in the brain has an important function in maintaining brain health. Blood circulation provides the brain with the oxygen and nutrients it needs to function properly.
Blood carries oxygen and glucose to the brain. The brain makes up only a small part of your total body weight, but it requires a lot of energy to function. The brain uses about 15% of the oxygen and glucose the body needs. In short, blood flow to the brain is a very important factor in maintaining brain health. If this cycle is disrupted, the brain can be damaged. As a result, many diseases and disorders related to nerve function can occur.

Hormones are the intercellular signal discharged into the blood by specific cells, they travel some distance in order to reach their target tissues and to perform other specific activities. Autocrine refers to the intercellular signals, which are discharged by the cells in a local area and affects the activity of the similar type of cell from which it was discharged.
Paracrine refers to the intercellular signals, which are discharged by the cells and influences other kinds of cells locally without being transported into the blood. Pheromones refer to the intercellular signals secreted into the surrounding and change the behavior and physiology of other individuals.
Neurohormones or neurotransmitters are the intercellular signals produced by the neurons. Of the mentioned intercellular signals, the "e" signifies neurotransmitter.
