The veins are responsible for carrying deoxygenated blood back to the heart from the tissue capillaries. Venous blood contains high levels of carbon dioxide and metabolic waste collected from the disposed tissues, and the blood is reoxygenated as it flows through the entire circulatory system. The veins help dispose of around 90% of waste fluid, provided there is no incompetence present.
The venous system has three types of veins, deep, superficial, and perforating. The deep veins lie within the muscles, are parallel to a neighboring artery, and are responsible for carrying 80-90% of the blood back to the heart. Using the muscles, helps with a significant venous return by reducing the pressure on the vein walls from the volume of blood within; as the muscles contract, it pushes the blood along the vein towards the heart, reducing the venous pressures. Superficial veins lie within the more superficial tissues and are responsible for draining the skin and subcutaneous tissues. The pressure in the superficial veins is less than in deeper veins. Perforating veins connect the deep and superficial veins throughout the lower leg.
Venous leg ulcers occur due to venous insufficiency in the adult population. Venous leg ulcers are accountable for significant prevalence among all leg ulcerations. Treatment includes leg elevation, compression, and proper wound care. It's essential to have any venous ulcers checked right away by your wound care specialist.
