Introduction
Knowledge of life-blood circulation always requires precise analysis and selection. Because of this, many people use blood supply to the brain flowchart to make it easier to remember. Medical studies will become more vivid and memorable.
It is a useful tool to help you visualize the routes of blood. Whether it serves the purpose of treatment or teaching, it can promote its advantages. Thus, this type of flowchart is usually used in the medical field.
Overview Of Blood Supply To The Brain
Definition
Blood supply to the brain refers to the process by which blood flows to the organs inside our head. The branches of the arteries will carry out this circle. It is an important process that ensures the maintenance of our brain and our body structures.
Loss of blood supply or aberrant blood supply leads to a dangerous condition for the brain and body organs.
Blood supply to the brain flowchart is a visual tool to depict this process. A flowchart with symbols, shapes, images, or colors will be more effective and make it easier to absorb, filter, and remember more important information.
Application
You can apply this flowchart in school lectures, scientific research, or medical seminars. Other important applications are to design, research, and make treatment plans for many diseases. The brain, arteries, or cancer treatment have the basement from this flowchart.
Benefits
Visual description is one of the most obvious benefits of flowcharts. This is why it is so popular in demonstrating adequate blood supply to the brain. This circulation is very complex, so vivid images will help you make an impression and remember it longer.
Coordination and sequence are also an advantage of these types of flowcharts. They help you connect the steps in a process or project in a logical order. Using a flowchart helps you understand blood flow regulation. The diagram will simplify the process when finding the connections between them.
Besides, visual flowcharts also help increase the efficiency of analysis and selectivity. Thanks to it, you can categorize, filter the necessary data, and remove redundant details.
Blood Supply To The Brain Flowchart
Blood transfusions to the brain are through two types of blood vessels. Two internal carotid arteries form the anterior cerebral circulation. At the same time, two vertebral arteries shape the posterior cerebral circulation.
Anterior Circulation
The anterior circulation includes the anterior cerebral artery (ACA) and the middle cerebral artery (MCA). They arise from the bifurcation place of the internal carotid artery at the circle of Willis.
Anterior cerebral arteries are the medial branches of the internal carotid artery. The two anterior cerebral arteries connect to form the anterior half of the Willis circle. After that, the anterior cerebral artery continues to divide into many sub-branches.
The ACA supplies blood to the sensory cortex and the center that controls urination. The MCA is the external branch of the internal carotid artery. It supplies blood to most of the cerebral hemispheres and the underlying subcortical structures.
Cerebral perfusion regions include the whole motor, sensory cortex, and expressive language area. The visual ray, language receptive area (Wernicke region) also receive life-blood from MCA.
Posterior Circulation
Our posterior brain consists of three parts, the occipital lobe, the cerebellum, and the brain-stem. Blood flows here through two branches of the vertebral artery that run along our spine. The vertebral artery begins to divide into many smaller branches after carrying blood cells to the posterior brain.
The anterior artery and superior artery provide a strong blood supply to the midbrain and cerebellum. Besides, the midbrain and cerebellum also receive blood from the Pontine branches. The posterior and posterior communicating arteries conduct blood transfusions to the posterior region.
Inside the skull, the two branches of the artery will merge to form the basilar artery.
The Circle Of Willis
The circle of Willis is an arterial structure in the form of a heptagon, situated at the base of the brain. This circle is also known as the cerebral artery ring. The communicating branches of the internal carotid and basilar arteries form from this ring.
The anterior and posterior communicating arteries are the parts of the circle of Willis. Besides, the proximal segment of the anterior, middle, and posterior arteries join in forming this circle
The ring creates connections between blood vessels. It also helps balance blood flow between the two sides of the brain (left and right hemispheres). The function of the Willis circle is to provide an alternative route if there is a blockage of blood cells.
We can take an example of an obstruction in the left anterior artery. At this time, the resilient blood supply cannot reach the cells by the left anterior part. However, the circle of Willis creates a substitutional pathway for circulation. The oxygen-rich blood can flow to these areas from the right internal carotid artery.
