the blood in the leg does not return back to the femoral vein as efficiently. Depending on the extent of valvular insufficiency, blood may pool in the lower parts of the leg and engorge the veins of the leg.
Explore the structure and function of veins, their relation to arteries, and common conditions related to vein health.
Anatomy Broadly, the veins of the lower extremity are divided into three systems confluent in a single network, which ultimately drains into the external iliac vein. This venous network includes the superficial veins, deep venous system, and their mutual connections, as well as the perforators (...
The two largest veins in the body are the superior vena cava, which transports blood from the upper body to the right atrium of the heart, and the inferior vena cava, which transports blood from the lower body to the right atrium. Blood vessels have three layers. The tunica adventitia (ou...
The reader approaching a text on the subject of sclerotherapy may be forgiven for wondering why it should be necessary to read through a revised account of human venous anatomy. Can the arrangement of the veins of the leg have changed much since the time of Gray, let alone since the last ...
