Although all systems in the body are important, the circulatory system is considered to be one of the most vital since it helps in the transportation of the nutrients and necessary components to the different systems of the body to work or function normally. The circulatory system is mainly composed of three basic parts. First is the heart, which is the one responsible for pumping; the blood vessels, which act as the channels that connect one body part to another; and the blood, which is a vital component in the functioning of the human body. So in order for us to understand this better, let us try to dwell upon the different organs of circulatory system including their different roles and purposes.
When we talk about the circulatory system of the body, there are actually two primary divisions. One is called the pulmonary circulation, which helps in the transportation of the blood to the heart from the lungs and vice versa. This type of circulation does not include any other parts or organs in the body. The second type; however, is called the systemic circulation since it carries the heart from the blood to the rest of the organs in the body and vice versa. Both of these circulations function at the same time since one way or the other, both divisions are still linked together. So what are the main organs of the circulatory system?
If we were to see the picture as a whole, we can conclude that the heart is the only organ involved in this whole of circulation, technically. Aside from the lungs in the pulmonary circulation, the heart is the only recognized organ that runs or works the circulatory system. This is the reason why the heart is considered as one of the most important organs in the body. However, this organ will not function very well without the use or the help of the blood vessels, the lungs and the blood.
The heart is composed of four chambers namely the right and left atria above, and the right and left ventricles below. The main task of the heart is to deliver the blood to the rightful location in our body. As blood enters the right atrium through the vena cavas, it will enter the right ventricle, where it is pumped towards the lungs for oxygenation processes. Once done, the blood will go back to the heart via the pulmonary vein entering the left atrium down to the left ventricle, which is the largest chamber of the four since it is the one responsible in pumping the blood towards the systemic circulation. This is basically the routine flow of our heart in the blood circulation in our body.
Another important organ in the circulation, as mentioned above, includes the lungs, which helps in oxygenating the blood and removing the waste back into the atmosphere. Without the lungs, the blood being circulated will become useless, thus causing us many health problems. The blood and blood vessels are also important components since they act as the passageway and the passengers of the circulation. Without these components, nutrients and essential products needed by our tissues all over the body will not be disseminated properly causing many serious complications and problems.
These are just some of the important organs that compose our circulatory system. Although the heart is considered to be the most essential part, the circulation will still not work effectively without the help or the aid of the other sub organs in the circulatory system as mentioned above.
