Coronary Circulation Of The Blood
Finding the Right Circulation Boost
Coronary Circulation: While these two words might sound extremely daunting to you, you will soon realize that they are really not! When it comes to biology, most people find the cardiovascular system extremely complicated.
However, you need not worry at all. Coronary circulation simply refers to the blood flow that happens inside the heart and among everything else that surrounds it. Through this article, you will know in detail what the anatomy involved in this circulation is, and each contributes to the other.
To break this down, coronary means anything that relates to the arteries and blood supply. Whereas circulation simply means the flow and movement, in this case of the blood.
Coronary Circulation: The Basics
Simply put, coronary circulation is the flow of the blood within the blood vessels. These vessels eventually supply blood to the muscle of the heart— which is also known as the myocardium in technical language.
When it comes to the coronary arteries, they are responsible for getting the oxygenated blood to the heart. Whereas the job of draining the blood after it is deoxygenated lies with the cardiac veins. It should come as no surprise to you that our entire body needs oxygenated blood at all times.
When it comes to the brain, it must always be kept oxygenated because it is responsible for a lot of other major functions that are carried out in the body. This, in turn, means that the heart must steadily but regularly supply blood without any hindrances or issues.
In case there do exist any problems with the same, then this can manifest in the form of an acute or chronic disease. This essentially includes heart attacks, which are also known as myocardial infarctions. This is where the heart muscle fails to operate due to a lack of oxygen.
When it comes to the human heart, which we are speaking of here, there are two coronary arteries that hail from the aorta. These are found right beneath the semilunar valves of the heart. When diastole takes place, an excess pressure forces blood into the coronary arteries of the heart.
Post this, the deoxygenated blood once again finds its' place in the chambers of the heart through the coronary veins. Most of this is then drained into the right atrium. While this may seem difficult, you will be surprised to know that this process is carried out with every breath like clockwork. Doesn't it sound interesting?
Let’s Talk Numbers
When it comes to taking in oxygen, the heart generally removes almost 75% of it from the blood during coronary circulation. This is essentially a lot more than the amount that is extracted through all of the other organs during circulation. For instance, only 40% is taken out of skeletal muscles.
An even lesser amount is extracted from the liver, around 20%. Therefore, you must have understood by now that deprivation of this amount of oxygenated blood could also lead to death in some cases.
The Deeper Process
The coronary vessels that supply the blood to the heart essentially look like a crown, thus getting the name coronary. Coronary circulation further consists of the arterial supply, venous drainage, and lymphatic drainage.
Furthermore, the cardiac vein includes the great cardiac vein, the small cardiac vein, the middle cardiac vein, the smallest cardiac vein, as well as the anterior cardiac vein.
Almost all of the blood found in the coronary vein is that which is returned through the coronary sinus. However, in the end, all of these veins are interconnected and responsible for removing deoxygenated blood.
What's extremely astonishing about coronary arteries, on the other hand, is that they are capable of so much by themselves.
When they are at their best, they can automatically regulate their entire process so that the blood flow levels are maintained. Not only that, but they also ensure that the levels remain appropriate. Isn’t it almost magical?
Furthermore, when these narrow blood vessels that make up the artery are blocked, they can also lead to angina or a heart attack. In most cases, this can happen due to atherosclerosis.
Just like the coronary veins, what is common amongst all coronary arteries is their ability to carry rich, oxygenated, and fresh blood so that everybody part can fulfill its' requirement.
Failure Of Circulation
Unfortunately, not every heart can always be perfect. The chances are that something will go wrong within the arteries or the vessels, causing some sort of temporary or permanent damage.
When this happens, and there is something amiss within the process of coronary circulation, it is known as coronary artery disease. In this condition, cholesterol or fatty deposits are built up inside the arteries.
Due to these deposits acting like a tough clog, the blood cannot be transported smoothly and efficiently. This blockage acts in such a way that transporting the blood to the heart becomes impossible.
Now, let’s also look at some of the symptoms of coronary artery disease so that you become even more familiar with the condition and can differentiate it from other diseases.
A person suffering from the same might experience dizziness, nausea, sweating, weakness, severe palpitations, etc. In case one experiences any of the following, it is best to consult a doctor.
Wrapping It All Up
Now that you know what is actually going on within that body of yours make sure to remember all of this well. You never know when you might need to recall what your heart does!
