Blood Circulation by Seilesh

Blood Circulation

The blood circulation system is made up of liquid plasma, cells, blood vessels, and the heart. In humans, the blood circulation system is cardiovascular, meaning the heart pumps blood to and from the various organs and parts of the body. The blood circulation in humans, discovered first by Harvey, is crucial for the proper functioning of the body. The aim of blood circulation is to pump oxygen rich blood to various parts of the body and bring back the impure or deoxygenated blood, back from the organs to heart. The heart pumps blood back and forth from the body organs.


The heart is made up of four chambers, the upper chambers are the auricles and the lower chambers are known as ventricles. The auricles and ventricles are separated from each other by AV valves, while arterial valves separate the ventricles from the arteries.

Blood Vessels

The blood vessels are the arteries, veins and capillaries.

Arteries carry blood from the heart to the other parts of the body. The arteries have elastic walls that are able to expand. The aorta is the large artery that starts out from the heart. It branches out into smaller arteries that in turn form arterioles and capillaries.

Veins carry blood to the heart from the various organs of the body.

Capillaries are thin blood vessels that branch out from the arteries and veins and carry blood to smaller areas of the body.

The circulatory system

A healthy human heart contracts at the rate of 70 contractions per minute. The blood circulation is made of two cycles, the systolic and the diastolic.

Systolic: The systolic blood system comes into action when the heart contracts. Upon contraction, the oxygen rich blood from the heart is pumped out into the arteries, from where it is sent to all the organs of the body. The AV node initiates the contraction through a nerve signal, for this reason it is called the “pacemaker” of the heart.

Diastolic: The diastolic circulation starts when the veins send deoxygenated blood from the organs of the body back to the heart through a contraction mechanism. The heart is in its “relaxed” phase then, that is, the period between two consecutive contractions.

Chiropractic and Blood Circulation

Chiropractic techniques help to better the blood circulation system to reduce swelling, soft tissue injuries and other disorders of the body. Increased blood circulation also reduces the blood pressure by bringing down the rate of heart beat. Better circulation means removal of toxic wastes from the body by the blood, as well as better supply of oxygen rich blood to the body.
