Circulatory System: Between Life and Death

While the heart is one of our most vital organs, it does more than carry fresh blood to different organs. The heart is the source of delivering oxygen and nutrients to cells and removing waste products such as carbon dioxide. For example, when the left ventricle pumps blood into the aorta, the blood travels through the arteries and into the capillary network in the lungs. Here, there is an exchange of oxygen and carbon dioxide, and nutrients, and other waste products. The used blood will then enter the right ventricle, into the pulmonary artery, and form a network of capillaries surrounding the pulmonary vesicles. Carbon dioxide and other waste products are released from the blood and then exit out of our system by exhalation.


Why Is It so Specific? Well, it isn’t just the heart that is working independently to circulate blood and oxygen throughout your body. The circulatory system is composed of your heart, blood, blood vessels, and other organ systems that co-play in making your body stably function.


What Role Do Our Right and Left Ventricles Play?


The right ventricle receives deoxygenated blood because most of the oxygen has been used up by the brain and other organs. With the assistance of your lungs, blood sustains a fresh supply of oxygen. This blood will be pumped to the rest of your body. The heart is incredibly essential to our body that it can control how much blood each organ will obtain. More specifically, with the support of hormones, blood vessels can widen and narrow themselves depending on how much a certain organ demands.


Is The Heart Fast Enough?


Depending on the organ’s need for blood, the speed at which the heart will pump blood will vary. For the heart to pump blood rapidly, your body has to be under pressure and it will increase if you do any form of physical activity.


Therefore, the circulatory system plays a vital role in not only keeping our bodies stable and alive but fulfilling the duties to transport oxygen-rich blood throughout the body, remove waste products, and perform its functions quickly and efficiently.
