Despite of the fact that venous diseases affect one-third of the general population, a lot still remains unclear about the venous system. Medical professionals or students need to develop an understanding of the venous system as any changes in it can affect the functioning of the heart. Motion of blood in venous system have a great impact on the volume of blood entering the heart. In a healthy situation, a heart cannot pump more blood than the amount that has be delivered to it.
Generally what veins or venous system does is move nutrient poor blood away from the organs and back to the heart to get it oxygenated. While we know the basics, let’s look at the more in-depth information we have on the venous system and the motion of blood in venous system.
Information We Know About the Venous System and the Motion of Blood in Venous System
Superficial Venous System
These veins are on the surface and may show through your skin. They collect blood from the skin and upper layers of the tissue. However, only a small percentage of the blood is returned to the heart through the superficial veins.
Great Saphenous Vein
Although, the saphenous vein is also a part of the superficial venous system, is much more significant. It is present in the foot and runs till the groin where it connects to the deeper vein system. This vein is the first to be treated when someone suffers from venous disease.
Small Saphenous Vein
Just like the great saphenous vein, the small saphenous vein too starts at the foot. It runs from outside of the foot till the knee. There in the knee, it joins the deeper vein system. After the great saphenous vein, it is the second most important vein doctors operate to treat venous disease.
Deep Venous System
Much like the name, deep veins run deep underneath the tissues and are the most significant part of the venous system in the human body. For instance, deep veins present in the legs are responsible for carrying most of the de-oxygenated blood from the legs to the heart.
These are the veins that connect the superficial veins to the deep veins. They make sure that enough blood is transported into the deep veins rather than just staying in the superficial veins.
While we know a lot about the different veins and their functions, Dr. B Rai’s discovery about the motion of blood in venous system is indeed new and fascinating. Dr. Rai discovered the motion of venous valves i.e. a rhythmic opening and closing with each cardiac heartbeat. This new information on the pulsatile motion of venous blood has debunked the previous assumption of venous blood to be in linear flow. It is a great discovery that further creates possibilities for more related studies in the field.
