In this article, I will explain the “large saphenous vein” in detail.
The saphenous vein is one of the large veins that passes through the part close to the surface of the body, and mainly plays an important role in returning blood from the lower limbs to the heart. This article provides knowledge about the structure, function, and health implications of the large saphenous vein. In addition, we will touch on diseases that are easily affected by the large saphenous vein and how to prevent them, and introduce precautions in daily life. Please use this article to deepen your understanding of the body.

What is the large saphenous vein
The large saphenous vein (large saphenous vein) is one of the main veins in the human body, and is particularly responsible for carrying blood from the lower limbs to the heart. By using a human anatomy diagram, it is easier to understand its location and flow path. The saphenous vein starts from the dorsal foot venous network, goes up through the foot, shoulder, and thigh to the groin, and eventually joins the femoral vein.
How to read large saphenous vein
The correct way to pronounce this vein is “dai fukuzai jomyaku.” In the medical world in particular, it is important to use accurate readings and terms.
Characteristics of the large saphenous vein
The most characteristic of the large saphenous vein is that it is located close to the surface of the human body. This has the advantage that conditions such as varicose veins are easily visible from the outside, and it is easy to diagnose when treatment is necessary.
Location/location of the large saphenous vein
In human anatomy diagrams, the saphenous vein is usually depicted as a vein that starts from the dorsal foot venous network, passes through the inner knee, and rises up the inside of the thigh. It then joins the femoral vein, which is located deep in the body in the groin. By using a human anatomy chart, it is possible to confirm its precise location.
How to remember the large saphenous vein
The path of the large saphenous vein is easy if you remember that it “rises from the bottom of the foot to the inside of the thigh.” Additionally, “large” in the name of a vein means that it plays a major role in the body, and “supine” means that it is close to the surface.
English and Latin for large saphenous vein
It is expressed as “Great Saphenous Vein” in English, and “Vena Saphena Magna” in Latin. It is common to use these terms in medical literature and in places of international exchange.
Trivia about the large saphenous vein
The saphenous vein is a very clinically important vein, such as being used in bypass surgery to treat varicose veins and cardiac surgery. Also, the branching pattern of the large saphenous vein may differ from person to person, and one characteristic is that there are large individual differences.
Tissues associated with the large saphenous vein: subcutaneous features of the lower extremities
The subcutaneous tissue of the lower extremities is composed of a fine layer of fat and multiple connective tissues, and a large amount of blood vessels and nerves, starting with the large saphenous vein, are distributed internally. This fat layer plays a role in regulating body temperature and protecting against external shocks. Furthermore, blood vessels and nerves that pass through this tissue contribute to various physiological functions, such as supplying nutrients to the lower extremities and transmitting sensory information.
Tissues associated with the large saphenous vein: location and position under the epidermis of the lower extremities
Specifically, the subcutaneous tissue of the lower limb, where the large saphenous vein is located, starts from the dorsal foot venous network, passes through the inner ankle, and goes up the inside of the knee and the front of the thigh. In particular, in the area above the knee, the large saphenous vein passes closer to the surface and eventually joins the femoral vein in the groin. This path is also very important from the viewpoint of the structure and function of the human body, and it greatly contributes to the hemodynamics of the lower extremities.
Tissues associated with the large saphenous vein: trivia under the epidermis of the lower extremities
The subcutaneous tissue of the lower extremities through which the large saphenous vein passes not only returns blood to the heart, but also plays an important role during leg trauma. This tissue supplies necessary nutrients and oxygen during the repair process during damage and promotes healing. Furthermore, the subcutaneous tissue of the lower extremities involving the large saphenous vein also plays a major role in the development of the disease called varicose veins. If the valve that prevents backflow of blood in the veins becomes defective, blood may stagnate in the veins and varicose veins may form.
Great saphenous vein quiz and correct answers
Q1.When the saphenous vein returns blood to the heart, what deep vein eventually merges?
Correct answer: This is the femoral vein.
summary
This time, I explained the location and location of the “large saphenous vein”, how to memorize it, and the English/Latin notation.
How was it?
I would be happy if reading this article deepened my understanding of anatomy.
