👉 The legs fluid, also known as the deep venous system, is a complex network of veins that plays a crucial role in maintaining blood circulation and pressure within the lower extremities. Comprising large, thin-walled veins that gradually branch into smaller ones, it returns deoxygenated blood from the legs, feet, and genital areas back to the heart. This system includes major veins like the femoral vein, popliteal vein, and tibial veins, which work together to counteract gravity's pull and ensure efficient blood flow. The legs fluid also contains valves that prevent blood from flowing backward, thus maintaining unidirectional circulation and preventing venous insufficiency or deep vein thrombosis.
