The human body is a complex system that is made up of many different components that allow it to function properly. Among the most vital components in the body are the veins. They are pathways that help to transport blood throughout the body to the vital organs and through the heart. The human cardiovascular system is made up of many veins that help circulate blood and nutrients throughout the body.
Veins, unlike arteries, are low-pressure systems that depend on muscle contractions to keep the blood flowing. Like all organs, they are susceptible to failure that can be caused by range of medical conditions and diseases. For instance, blood clots can prevent veins from transporting the appropriate amount of blood.
Types of Veins
There are mainly 4 kinds of veins. You have pulmonary veins that transport blood from the lungs to the heart’s left atrium. Then, you have systemic veins that transport oxygen-depleted blood from various organs to the heart’s right atrium.
You also have what are known as superficial veins that are located right beneath the skin. These veins do not have a corresponding artery located close to them.
Finally, you have deep veins that are situated within muscle tissue and they are located close to a corresponding artery. They usually form a close-knit system that often goes by the same name. For example, the coronary veins and coronary arteries.
There are primarily three layers that make up a vein.
The first layer is called the tunica adventitia, which is the outer layer. This is the thickest of all three layers and is composed of loose connective tissues and an elastic membrane on the outside. The tunica adventitia combines with the surrounding tissues.
The second layer is the tunica media. This is the middle layer and is made up of elastic fibers, smooth muscle fibers, and collagen.
The last and third layer is the tunica intima. This is the thinnest layer of the three and is made up of connective tissue and elastic membrane on the inside. But, the tunica intima itself contains another layer called the endothelium, which is exposed to the blood flow. So, when there is venous insufficiency, the endothelium is the first layer to become affected.
Venous Insufficiency and Weakness
The veins, as stated earlier, are susceptible to several conditions brought on by factors such as age, exertion, giving birth, and genetics. Typically, these conditions can cause the walls of the vein to swell or expand, hindering proper blood flow. As a result, the veins essentially become ineffective.
This leads to the heart receiving less blood than usual. The leftover blood starts to form pools and leads to a condition called Varicose Veins, which can be incredibly painful. If ignored, the veins will eventually start to degenerate.
So, it is of the utmost importance for people to take care of their veins. Ideally, this includes practicing healthy habits such as exercising, consuming nutritious food, avoiding the excessive consumption of sugar, sodium, or fats, and also avoiding tobacco/smoking.
However, if you do feel that you may be affected with Varicose Veins, there are non-surgical and surgical treatment options to correct the issue. Talk to your surgeon for more information and a proper diagnosis.
